Artemis 2 Updates, Cosmic Iron Bars, and the Role of Hydrogen Cyanide in Life's Origins

In this exciting episode of Space Nuts, hosts Andrew Dunkley and Professor Fred Watson delve into the latest developments in space exploration and cosmic phenomena. Join them as they discuss the progress of the Artemis 2 mission, the discovery of a mysterious iron bar in the Ring Nebula, and the intriguing role of hydrogen cyanide in the potential origins of life.

Episode Highlights:

- Artemis 2 Progress: Andrew and Fred provide an update on the Artemis 2 mission, which recently moved to launch pad 39B at Cape Canaveral. They discuss the upcoming wet dress rehearsal and the significance of this mission as a precursor to future lunar explorations.

- The Iron Bar Mystery: The hosts explore a fascinating discovery in the Ring Nebula, where scientists have identified a linear structure made of highly ionized iron gas. They discuss its potential origins and what this could mean for our understanding of planetary nebulae.

- Hydrogen Cyanide and Life: Andrew and Fred examine a study suggesting that hydrogen cyanide, often seen as a deadly substance, may play a crucial role in the formation of prebiotic molecules. They ponder the implications for life on other celestial bodies, such as Titan.

00:00:00.240 --> 00:00:02.149
Hi there. Thanks for joining us again.


00:00:02.159 --> 00:00:04.390
This is Space Nuts, where we talk


00:00:04.400 --> 00:00:06.309
astronomy and space science every week,


00:00:06.319 --> 00:00:09.110
twice a week, in fact. On today's


00:00:09.120 --> 00:00:11.110
episode, we're going to look at the


00:00:11.120 --> 00:00:13.830
progress of Arteimus 2. There's an


00:00:13.840 --> 00:00:16.230
update for you, and it's good news. Uh,


00:00:16.240 --> 00:00:19.029
this is a weird story. An iron bar seen


00:00:19.039 --> 00:00:21.830
in space. And no, it is not a runaway


00:00:21.840 --> 00:00:23.349
spanner from the International Space


00:00:23.359 --> 00:00:26.070
Station, although that does happen. and


00:00:26.080 --> 00:00:28.950
something deadly that could be important


00:00:28.960 --> 00:00:31.189
in the origin of life. We'll find out


00:00:31.199 --> 00:00:33.830
about that on this episode of Space


00:00:33.840 --> 00:00:34.709
Nuts.


00:00:34.719 --> 00:00:39.510
>> 15 seconds. Guidance is internal. 10 9


00:00:39.520 --> 00:00:41.270
Ignition sequence start.


00:00:41.280 --> 00:00:42.229
>> Space Nuts.


00:00:42.239 --> 00:00:47.110
>> 5 4 3 2 1 2 3 4 5 5 4 3 2 1


00:00:47.120 --> 00:00:48.310
>> Space Nuts.


00:00:48.320 --> 00:00:51.350
>> Astronauts report. It feels good. Back


00:00:51.360 --> 00:00:53.750
for more with stories galore is


00:00:53.760 --> 00:00:55.510
Professor Fred Watson, astronomer at


00:00:55.520 --> 00:00:57.510
large. Hello, Fred.


00:00:57.520 --> 00:00:59.990
>> Good morning, Andrew. Or good good


00:01:00.000 --> 00:01:01.590
whatever part of the day it is when


00:01:01.600 --> 00:01:03.110
you're listening to this.


00:01:03.120 --> 00:01:05.109
>> Yes. It's difficult dealing with a


00:01:05.119 --> 00:01:06.630
global audience, isn't it? Because you


00:01:06.640 --> 00:01:07.830
just don't know.


00:01:07.840 --> 00:01:09.270
>> You just don't know what time it is


00:01:09.280 --> 00:01:10.390
wherever.


00:01:10.400 --> 00:01:13.750
>> But uh they know what time it is here.


00:01:13.760 --> 00:01:16.230
>> Well, it's Eastern summertime is what it


00:01:16.240 --> 00:01:19.270
is. And uh we are approaching the


00:01:19.280 --> 00:01:22.390
hottest time of the year in this part of


00:01:22.400 --> 00:01:24.469
the world. And I've been looking at the


00:01:24.479 --> 00:01:26.950
forecast, Fred, cuz uh right now it's


00:01:26.960 --> 00:01:30.710
not too bad. You know, low low to mid30s


00:01:30.720 --> 00:01:32.710
uh Celsius, which some people would be


00:01:32.720 --> 00:01:34.550
horrified by, but for us that's pretty


00:01:34.560 --> 00:01:37.670
normal. But next week,


00:01:37.680 --> 00:01:41.190
we are expected to hit a string of 40


00:01:41.200 --> 00:01:44.550
plus temperatures peaking at 45.


00:01:44.560 --> 00:01:46.069
45


00:01:46.079 --> 00:01:48.630
which is uh I for those who don't use


00:01:48.640 --> 00:01:52.069
the metric system that is 113 degrees


00:01:52.079 --> 00:01:53.670
Fahrenheit.


00:01:53.680 --> 00:01:56.389
So that's um that's what's coming up for


00:01:56.399 --> 00:01:57.990
us. I mean some people will hear this


00:01:58.000 --> 00:01:59.670
and it will already have happened and we


00:01:59.680 --> 00:02:00.950
won't be there next week and they'll


00:02:00.960 --> 00:02:02.630
wonder why. Well, that's the answer.


00:02:02.640 --> 00:02:06.630
We're just going to burn. We are burn.


00:02:06.640 --> 00:02:08.550
>> Uh yeah, horrific. It's been horrific.


00:02:08.560 --> 00:02:10.309
We had a massive storm here the other


00:02:10.319 --> 00:02:12.790
day and it uh ripped through the the


00:02:12.800 --> 00:02:14.309
city. I actually looked at it on the


00:02:14.319 --> 00:02:16.630
radar and it was only a really small


00:02:16.640 --> 00:02:17.830
cell,


00:02:17.840 --> 00:02:20.470
>> but gee, it was intense. It absolutely


00:02:20.480 --> 00:02:22.470
devastated the golf course. We lost a


00:02:22.480 --> 00:02:24.630
lot of trees and branches. Uh, but it


00:02:24.640 --> 00:02:27.350
happened all over town. So, yeah, we've


00:02:27.360 --> 00:02:29.190
had some uh pretty radical weather of


00:02:29.200 --> 00:02:30.470
late and now we're going to hit a heat


00:02:30.480 --> 00:02:32.630
wave and I don't I think we've got like


00:02:32.640 --> 00:02:36.630
six or seven days in a row at least over


00:02:36.640 --> 00:02:39.589
the old 100 Fahrenheit.


00:02:39.599 --> 00:02:40.150
So,


00:02:40.160 --> 00:02:41.110
>> there you go.


00:02:41.120 --> 00:02:43.110
>> Looking forward to that.


00:02:43.120 --> 00:02:44.630
Yes, I'm sure you are. It's a bit more


00:02:44.640 --> 00:02:46.790
temperate here on the coast, but uh we


00:02:46.800 --> 00:02:49.110
did have a day weight last Saturday


00:02:49.120 --> 00:02:52.150
where it it was 43 was the highest I I


00:02:52.160 --> 00:02:54.309
saw when I was out and about and it's


00:02:54.319 --> 00:02:56.790
been quite a few years quite a few years


00:02:56.800 --> 00:02:58.869
since we had a 45 here, but I do


00:02:58.879 --> 00:03:01.430
remember one some years ago and it Yeah,


00:03:01.440 --> 00:03:03.270
it was horrible. They actually forecast


00:03:03.280 --> 00:03:05.589
47 or 48 that day and it didn't get


00:03:05.599 --> 00:03:07.350
there thankfully.


00:03:07.360 --> 00:03:09.830
>> But um hopefully it won't do it again


00:03:09.840 --> 00:03:12.390
this year. But u it's been a long time


00:03:12.400 --> 00:03:14.149
since we've had temperatures like this.


00:03:14.159 --> 00:03:15.990
Um you


00:03:16.000 --> 00:03:17.509
for a few years in a row we didn't even


00:03:17.519 --> 00:03:19.270
make 40.


00:03:19.280 --> 00:03:20.869
But um yeah, we're we're getting at


00:03:20.879 --> 00:03:24.070
least four in a row next week.


00:03:24.080 --> 00:03:26.070
>> Anyway, um Oh, and the other thing


00:03:26.080 --> 00:03:28.630
that's been really exciting this week uh


00:03:28.640 --> 00:03:33.509
is um the auroral activity in you saw


00:03:33.519 --> 00:03:34.149
anything?


00:03:34.159 --> 00:03:36.550
>> No, I went out last night and didn't see


00:03:36.560 --> 00:03:38.789
anything. there's too much light and I I


00:03:38.799 --> 00:03:40.550
thought, "Oh, well, I go out of town."


00:03:40.560 --> 00:03:44.229
Uh, yeah. How far do I go? Where do I go


00:03:44.239 --> 00:03:45.990
to get a perch because it's pretty flat


00:03:46.000 --> 00:03:49.110
out here. Um, but I didn't see anything.


00:03:49.120 --> 00:03:52.390
There was one photo I took where it may


00:03:52.400 --> 00:03:54.869
there was a little bit of a purple sheen


00:03:54.879 --> 00:03:59.350
in the distance, maybe. I don't know.


00:03:59.360 --> 00:04:02.070
>> Last night, the night before was better.


00:04:02.080 --> 00:04:03.509
It was right.


00:04:03.519 --> 00:04:05.110
>> This morning, of course, I wake up to


00:04:05.120 --> 00:04:06.789
all these amazing photos that people


00:04:06.799 --> 00:04:09.350
have taken and they saw them as far


00:04:09.360 --> 00:04:11.830
north as southern Queensland. So,


00:04:11.840 --> 00:04:12.470
>> yeah, that's right.


00:04:12.480 --> 00:04:14.949
>> It's been a very intense solar storm


00:04:14.959 --> 00:04:17.509
that's um that's caused all this. But it


00:04:17.519 --> 00:04:18.789
looks like I missed the boat again,


00:04:18.799 --> 00:04:20.949
Fred.


00:04:20.959 --> 00:04:22.390
>> It's got to come with us to the Arctic


00:04:22.400 --> 00:04:22.950
sometime.


00:04:22.960 --> 00:04:25.990
>> Ah, look. Yeah. The other thing I saw


00:04:26.000 --> 00:04:29.990
this morning um was there's a um a trip


00:04:30.000 --> 00:04:32.070
to the Arctic this year to watch the


00:04:32.080 --> 00:04:35.189
solar eclipse. That'll be a big one. I


00:04:35.199 --> 00:04:37.909
think that's in um August.


00:04:37.919 --> 00:04:40.950
Is it? Or was that last year?


00:04:40.960 --> 00:04:45.030
>> Um no. Um there is I thought it was the


00:04:45.040 --> 00:04:46.070
Antarctic.


00:04:46.080 --> 00:04:46.870
>> Oh, it might be.


00:04:46.880 --> 00:04:49.270
>> Just kissed. Yeah, I think that's


00:04:49.280 --> 00:04:50.950
probably it. Yeah.


00:04:50.960 --> 00:04:53.430
>> Uh there's there is the there is an


00:04:53.440 --> 00:04:54.870
eclipse in August. It's the 12th of


00:04:54.880 --> 00:04:57.110
August. We'll be watching that from uh


00:04:57.120 --> 00:04:58.790
northern Spain.


00:04:58.800 --> 00:05:01.430
>> Um so we're taking one of M's tour


00:05:01.440 --> 00:05:03.189
groups up there to see the eclipse.


00:05:03.199 --> 00:05:04.310
>> Well, that's the one they were talking


00:05:04.320 --> 00:05:04.790
about.


00:05:04.800 --> 00:05:06.150
>> So that


00:05:06.160 --> 00:05:07.670
>> Yeah, I think the I think the one you're


00:05:07.680 --> 00:05:09.350
talking about was Antarctica and it's


00:05:09.360 --> 00:05:11.350
not the same eclipse. Anyway, never


00:05:11.360 --> 00:05:12.550
mind.


00:05:12.560 --> 00:05:14.469
>> Yeah, I can see the one the one I was


00:05:14.479 --> 00:05:16.150
thinking of is the one you're going to


00:05:16.160 --> 00:05:17.430
see in


00:05:17.440 --> 00:05:20.550
>> Okay. All right. Okay. might Yeah, might


00:05:20.560 --> 00:05:21.430
start in the Arctic.


00:05:21.440 --> 00:05:23.270
>> Yeah, it's crossing all the places we


00:05:23.280 --> 00:05:25.430
were visiting


00:05:25.440 --> 00:05:27.830
last year. So, we're all we're a year


00:05:27.840 --> 00:05:29.830
too early.


00:05:29.840 --> 00:05:30.390
Never mind.


00:05:30.400 --> 00:05:32.310
>> Always ahead of always ahead of the


00:05:32.320 --> 00:05:33.270
game. But


00:05:33.280 --> 00:05:34.950
>> yes, always get through Dodger before


00:05:34.960 --> 00:05:36.629
the disaster. That's what that's their


00:05:36.639 --> 00:05:38.150
philosophy.


00:05:38.160 --> 00:05:40.469
>> Um we've got a bit to get through. So,


00:05:40.479 --> 00:05:43.590
we'll we'll start with um this exciting


00:05:43.600 --> 00:05:45.749
news and that is an update on the


00:05:45.759 --> 00:05:47.270
Arteimus 2 mission. Now, we only


00:05:47.280 --> 00:05:50.629
mentioned that a week or so ago, uh that


00:05:50.639 --> 00:05:52.070
it was one of the big things happening


00:05:52.080 --> 00:05:55.029
in 2026. Uh it's starting to happen.


00:05:55.039 --> 00:05:57.749
They've started moving stuff.


00:05:57.759 --> 00:06:02.230
That That's right. Uh so um as we speak


00:06:02.240 --> 00:06:05.990
the uh Arteimus 2 stack, if that's what


00:06:06.000 --> 00:06:08.150
you call it, with the uh space launch


00:06:08.160 --> 00:06:10.950
system and its two solid rocket boosters


00:06:10.960 --> 00:06:14.710
and the uh service module, the the I


00:06:14.720 --> 00:06:16.710
nearly said Apollo there, the Orion


00:06:16.720 --> 00:06:20.070
capsule on top, uh is sitting on


00:06:20.080 --> 00:06:24.070
launchpad 39B, uh which is a very famous


00:06:24.080 --> 00:06:27.350
part of the launch facility at um at


00:06:27.360 --> 00:06:28.550
Cape Canaveral.


00:06:28.560 --> 00:06:31.350
So uh it yes it's made its journey from


00:06:31.360 --> 00:06:35.350
the uh vehicle assembly building uh to


00:06:35.360 --> 00:06:37.909
launchpad 39B


00:06:37.919 --> 00:06:39.670
which if I remember rightly is 6


00:06:39.680 --> 00:06:41.749
kilometers and it took 12 hours to do


00:06:41.759 --> 00:06:42.390
it.


00:06:42.400 --> 00:06:46.150
>> So half a kilometer per hour um uh is


00:06:46.160 --> 00:06:48.230
that right? Yes, that's right.


00:06:48.240 --> 00:06:51.350
>> Yeah, I think it's like 082 of a mile


00:06:51.360 --> 00:06:52.950
per hour or something like that.


00:06:52.960 --> 00:06:55.990
>> Yes, that's what I saw too. Um I think


00:06:56.000 --> 00:06:58.309
the when you average it out it it comes


00:06:58.319 --> 00:07:00.070
to half a kilometer an hour but I think


00:07:00.080 --> 00:07:02.469
it's a little bit more than that uh in


00:07:02.479 --> 00:07:04.950
terms of um you know the the maximum


00:07:04.960 --> 00:07:07.270
speed when it accelerated up to full


00:07:07.280 --> 00:07:10.550
speed 82 miles per hour. Uh so that is


00:07:10.560 --> 00:07:12.550
the start of the journey to the moon uh


00:07:12.560 --> 00:07:15.029
which is really quite nice. Um and


00:07:15.039 --> 00:07:18.950
Artimus 2 yes the mission uh will uh we


00:07:18.960 --> 00:07:22.469
hope uh actually launch within the next


00:07:22.479 --> 00:07:25.670
few months. What we do know is that


00:07:25.680 --> 00:07:30.070
there is to be um a wet uh what's what's


00:07:30.080 --> 00:07:34.309
called a a wet um test. Is that the


00:07:34.319 --> 00:07:37.589
right word? Uh a wet dress rehearsal.


00:07:37.599 --> 00:07:39.749
That's that's the correct term. Uh where


00:07:39.759 --> 00:07:43.990
it's fully fueled up uh and basically uh


00:07:44.000 --> 00:07:45.589
under goes a countdown, a dummy


00:07:45.599 --> 00:07:48.629
countdown. Uh everything as if you were


00:07:48.639 --> 00:07:50.710
about to launch, but you don't launch.


00:07:50.720 --> 00:07:53.350
Uh, and we're told that is not going to


00:07:53.360 --> 00:07:55.909
happen any later than basically next


00:07:55.919 --> 00:07:57.830
week our time or the week after next.


00:07:57.840 --> 00:08:01.029
Uh, which is February the 2nd is the


00:08:01.039 --> 00:08:04.070
date that we've got. So, um, that will


00:08:04.080 --> 00:08:06.710
be exciting to see how that how that


00:08:06.720 --> 00:08:09.350
goes, whether everything goes flawlessly


00:08:09.360 --> 00:08:11.990
or whether they find a gotcha and have


00:08:12.000 --> 00:08:13.830
to wheel it back to the vehicle assembly


00:08:13.840 --> 00:08:14.950
building which has happened.


00:08:14.960 --> 00:08:16.469
>> That's happened before, hasn't it?


00:08:16.479 --> 00:08:18.869
>> Yeah, it's it did with Arteimus one. In


00:08:18.879 --> 00:08:20.309
fact, I think it happened two or three


00:08:20.319 --> 00:08:23.029
times, didn't it? If I remember rightly,


00:08:23.039 --> 00:08:24.629
uh because they've got to get this right


00:08:24.639 --> 00:08:25.909
and they've got to, you know, it's got


00:08:25.919 --> 00:08:28.390
to be right and it will be. Uh is the


00:08:28.400 --> 00:08:29.830
bottom line. Yeah.


00:08:29.840 --> 00:08:32.630
>> Yes, indeed. But it's exciting. Um I


00:08:32.640 --> 00:08:33.829
think it has been delayed. It was


00:08:33.839 --> 00:08:36.550
supposed to go last year, wasn't it?


00:08:36.560 --> 00:08:38.790
>> Uh that's correct. Yes. Uh indeed,


00:08:38.800 --> 00:08:41.110
that's true. It's I mean that you know


00:08:41.120 --> 00:08:43.670
the whole project has uh suffered


00:08:43.680 --> 00:08:47.110
delays. Uh there is one bit of good news


00:08:47.120 --> 00:08:50.710
though which has come out of


00:08:50.720 --> 00:08:53.590
uh Congress. I think I should get my


00:08:53.600 --> 00:08:55.910
terms right. But the but the NASA


00:08:55.920 --> 00:08:59.430
funding uh for next year or for this


00:08:59.440 --> 00:09:03.430
year uh seems to be uh much more secure


00:09:03.440 --> 00:09:05.590
than was previously thought. Some of the


00:09:05.600 --> 00:09:07.910
big cuts that were being planned have


00:09:07.920 --> 00:09:10.470
sort of evaporated. Uh and I think the


00:09:10.480 --> 00:09:13.190
funding level for NASA this year uh is


00:09:13.200 --> 00:09:15.190
not that much. I think it's on a par


00:09:15.200 --> 00:09:18.389
with what they received last year. Um uh


00:09:18.399 --> 00:09:20.230
notwithstanding the fact that yes, the


00:09:20.240 --> 00:09:22.470
Mars sample return mission has has still


00:09:22.480 --> 00:09:24.949
been axed from that budget, but that


00:09:24.959 --> 00:09:27.269
leaves room for some other things to be


00:09:27.279 --> 00:09:29.590
funded and no doubt there'll be further


00:09:29.600 --> 00:09:32.230
talks on how we get these canisters of


00:09:32.240 --> 00:09:35.509
uh Martian soil back from Mars before we


00:09:35.519 --> 00:09:36.550
all die.


00:09:36.560 --> 00:09:37.190
>> Yes.


00:09:37.200 --> 00:09:41.030
>> Yeah. Well, hope now let's hope somebody


00:09:41.040 --> 00:09:43.509
um riding a trail bike up there one day


00:09:43.519 --> 00:09:45.030
comes across it and goes, "Oi, what's


00:09:45.040 --> 00:09:48.870
this? What's this? Who left this here?"


00:09:48.880 --> 00:09:51.750
Um but yeah, uh it's good news. Uh and


00:09:51.760 --> 00:09:53.990
we should mention the astronauts


00:09:54.000 --> 00:09:57.190
involved, Reed Wiseman, V Glover,


00:09:57.200 --> 00:10:02.230
Christina Ko, uh and they're all from uh


00:10:02.240 --> 00:10:04.310
NASA Americans. And then you've got uh


00:10:04.320 --> 00:10:06.389
from the Canadian Space Agency, Jeremy


00:10:06.399 --> 00:10:10.870
Hansen. And uh they'll be journeying out


00:10:10.880 --> 00:10:13.829
and around and back uh over a period of


00:10:13.839 --> 00:10:15.750
10 days, which is about the same length


00:10:15.760 --> 00:10:18.310
as the average Apollo mission. Although


00:10:18.320 --> 00:10:20.230
there was one mission that only went 5


00:10:20.240 --> 00:10:23.190
days because well, they couldn't stop


00:10:23.200 --> 00:10:24.069
because they


00:10:24.079 --> 00:10:25.269
>> Yeah, that's right.


00:10:25.279 --> 00:10:26.389
>> They had a bit of


00:10:26.399 --> 00:10:28.150
>> that was another story.


00:10:28.160 --> 00:10:30.949
>> But it's true. It's reminiscent of


00:10:30.959 --> 00:10:34.310
Apollo 8. uh you know by Christmas Day,


00:10:34.320 --> 00:10:35.670
wasn't it?


00:10:35.680 --> 00:10:37.509
>> Uh Christmas Eve, I think. I can't


00:10:37.519 --> 00:10:37.750
remember.


00:10:37.760 --> 00:10:38.870
>> Something like Christmas Eve. I think it


00:10:38.880 --> 00:10:39.990
was Christmas Eve. Yeah.


00:10:40.000 --> 00:10:40.389
>> Yeah.


00:10:40.399 --> 00:10:44.870
>> 1968. Um um but but what's different


00:10:44.880 --> 00:10:46.790
though is I think their orbits around


00:10:46.800 --> 00:10:49.829
the backside of the moon will be uh at a


00:10:49.839 --> 00:10:52.230
higher distance from the lunar surface


00:10:52.240 --> 00:10:55.190
than we saw with the Apollo mission. So


00:10:55.200 --> 00:10:57.990
uh these astronauts will be uh will hold


00:10:58.000 --> 00:11:01.269
a record as being the furthest humans.


00:11:01.279 --> 00:11:03.269
the furthest that humans have been from


00:11:03.279 --> 00:11:05.670
planet Earth after at the end of their


00:11:05.680 --> 00:11:06.389
mission. So


00:11:06.399 --> 00:11:08.150
>> yeah, that record currently held by


00:11:08.160 --> 00:11:10.389
Michael Collins.


00:11:10.399 --> 00:11:11.670
>> That is correct. Yes.


00:11:11.680 --> 00:11:14.150
>> Yes. I think in fact uh there's a famous


00:11:14.160 --> 00:11:16.069
photo I think I've mentioned before that


00:11:16.079 --> 00:11:19.110
Michael Collins took which showed the


00:11:19.120 --> 00:11:21.430
moon where Neil Armstrong and Buzz


00:11:21.440 --> 00:11:23.190
Aldrin were on the surface at the time


00:11:23.200 --> 00:11:25.590
and Earth in the background and it


00:11:25.600 --> 00:11:28.790
basically said every human being that's


00:11:28.800 --> 00:11:31.350
ever existed is in this photo except


00:11:31.360 --> 00:11:33.190
one.


00:11:33.200 --> 00:11:34.230
>> I think that's great.


00:11:34.240 --> 00:11:36.389
>> That was Yeah.


00:11:36.399 --> 00:11:38.949
>> Yeah. I mean you think


00:11:38.959 --> 00:11:40.069
>> to feel lonely.


00:11:40.079 --> 00:11:42.310
>> It's pretty Yeah. Yeah. It's pretty deep


00:11:42.320 --> 00:11:45.190
when you take a photo and someone says


00:11:45.200 --> 00:11:46.870
to you, "Lady, do you realize you're the


00:11:46.880 --> 00:11:49.590
only human human being in history that's


00:11:49.600 --> 00:11:52.230
not in that photograph?"


00:11:52.240 --> 00:11:54.310
I reckon that's uh that's incredible.


00:11:54.320 --> 00:11:56.310
Yeah. Uh of course, people come back and


00:11:56.320 --> 00:11:57.590
say, "Oh, but what about the people on


00:11:57.600 --> 00:11:58.470
the other side of the planet that


00:11:58.480 --> 00:11:59.670
weren't in the picture?" Well, they were


00:11:59.680 --> 00:12:01.269
on the planet, so they were in the


00:12:01.279 --> 00:12:01.670
picture.


00:12:01.680 --> 00:12:03.110
>> Yeah, we we knew.


00:12:03.120 --> 00:12:04.790
>> We could use a bit of creative license.


00:12:04.800 --> 00:12:05.269
Sure. We


00:12:05.279 --> 00:12:06.790
>> Yes, that's right.


00:12:06.800 --> 00:12:07.190
>> That's right.


00:12:07.200 --> 00:12:10.150
>> Um we should also mention why why this


00:12:10.160 --> 00:12:12.790
mission is happening. And it's it's it's


00:12:12.800 --> 00:12:17.110
based around putting long-term humans or


00:12:17.120 --> 00:12:19.110
long a long-term human presence on the


00:12:19.120 --> 00:12:21.509
lunar surface, but the ultimate goal is


00:12:21.519 --> 00:12:24.629
to create that springboard for missions


00:12:24.639 --> 00:12:28.069
to Mars. So it it's it's part of a


00:12:28.079 --> 00:12:30.710
long-term venture, I suppose.


00:12:30.720 --> 00:12:32.949
Yeah, I think actually that you know


00:12:32.959 --> 00:12:36.069
it's got an immediacy about it that um


00:12:36.079 --> 00:12:40.150
um is makes the Mars issue


00:12:40.160 --> 00:12:44.069
uh perhaps uh not reducing its


00:12:44.079 --> 00:12:48.150
significance but um but giving us a good


00:12:48.160 --> 00:12:50.069
you know a good reason to be on the moon


00:12:50.079 --> 00:12:52.230
anyway and that's the the possible


00:12:52.240 --> 00:12:53.590
resources that are on the moon.


00:12:53.600 --> 00:12:56.310
>> Yeah. Plus, there's still a geopolitical


00:12:56.320 --> 00:12:58.629
uh aspect of this, exactly as there was


00:12:58.639 --> 00:13:02.230
in the 1960s. Um, the Americans are very


00:13:02.240 --> 00:13:04.069
keen to get there before Chinese


00:13:04.079 --> 00:13:05.829
tyonauts walk on the lunar surface,


00:13:05.839 --> 00:13:08.150
which they're certainly planning to do


00:13:08.160 --> 00:13:11.110
by 2030. That is what we hear. But


00:13:11.120 --> 00:13:13.509
you're right. Um, I mean, Arteimus 2 is


00:13:13.519 --> 00:13:16.230
a is a precursor to Arteimus 3, which is


00:13:16.240 --> 00:13:17.910
likely to be not next year, but the


00:13:17.920 --> 00:13:19.269
following year. There's still a lot of


00:13:19.279 --> 00:13:21.350
work to do on that. uh where four


00:13:21.360 --> 00:13:23.190
astronauts will land on the lunar


00:13:23.200 --> 00:13:26.710
surface. And that in a in a sense is the


00:13:26.720 --> 00:13:28.310
perhaps the opening gambit for a


00:13:28.320 --> 00:13:30.790
permanent uh or a semi-permanent human


00:13:30.800 --> 00:13:33.110
presence on Mars. And yes, you're right.


00:13:33.120 --> 00:13:36.629
Eventually that will lead to we hope uh


00:13:36.639 --> 00:13:39.030
expertise that we can gather that will


00:13:39.040 --> 00:13:41.990
take astronauts to Mars, not to colonize


00:13:42.000 --> 00:13:45.430
it, but to explore it in a in a suitably


00:13:45.440 --> 00:13:46.710
ethical way.


00:13:46.720 --> 00:13:49.269
>> You you hope not to colonize it.


00:13:49.279 --> 00:13:52.310
>> Yeah. Well, that's right.


00:13:52.320 --> 00:13:55.990
>> Okay. Um, yeah, very exciting news and


00:13:56.000 --> 00:13:58.629
hopefully all will go well with the uh


00:13:58.639 --> 00:14:00.629
with the tests. Uh, in fact, they're


00:14:00.639 --> 00:14:02.069
talking about doing it more than once if


00:14:02.079 --> 00:14:05.670
they've got time. Um, but yeah, it'll be


00:14:05.680 --> 00:14:08.310
uh it'll be and it'll it'll bring about


00:14:08.320 --> 00:14:11.030
the same level of excitement, I suppose,


00:14:11.040 --> 00:14:13.189
that we enjoyed in the 60s with the


00:14:13.199 --> 00:14:14.790
Apollo missions because you got a whole


00:14:14.800 --> 00:14:16.790
new generation that weren't around to


00:14:16.800 --> 00:14:19.350
see that. And so this is all fresh and


00:14:19.360 --> 00:14:20.790
new for them.


00:14:20.800 --> 00:14:22.629
>> I reckon that that's right.


00:14:22.639 --> 00:14:26.150
>> That will revive the uh the interest in


00:14:26.160 --> 00:14:29.590
uh space science uh as well. I suppose


00:14:29.600 --> 00:14:31.350
uh if you'd like to read all about it,


00:14:31.360 --> 00:14:34.230
you can log on to Scitec Daily, but I


00:14:34.240 --> 00:14:35.750
think you'll probably find there's


00:14:35.760 --> 00:14:37.910
plenty of news on plenty of platforms,


00:14:37.920 --> 00:14:40.069
including the NASA website. This is


00:14:40.079 --> 00:14:41.829
Space Nuts with Andrew Dunley and


00:14:41.839 --> 00:14:45.030
Professor Fred Watson.


00:14:45.040 --> 00:14:46.790
Let's take a break from the show so I


00:14:46.800 --> 00:14:49.670
can tell you about our sponsor, NordVPN.


00:14:49.680 --> 00:14:52.470
With NordVPN, you can explore the web


00:14:52.480 --> 00:14:54.949
securely and privately, no matter where


00:14:54.959 --> 00:14:57.509
you are. Whether you're streaming space


00:14:57.519 --> 00:15:00.230
documentaries, downloading data from the


00:15:00.240 --> 00:15:02.629
International Space Station, legally of

>> Space nuts.


00:16:08.959 --> 00:16:12.389
>> Okay, Fred. Uh, this weird story has,


00:16:12.399 --> 00:16:15.189
uh, been published in a in a paper about


00:16:15.199 --> 00:16:18.710
a nebula that is demonstrating something


00:16:18.720 --> 00:16:21.189
that at this point in time is


00:16:21.199 --> 00:16:22.870
inexplicable.


00:16:22.880 --> 00:16:24.629
Uh, they know what it is,


00:16:24.639 --> 00:16:26.790
>> they don't know why it is.


00:16:26.800 --> 00:16:29.829
>> Yeah. Exactly. And so this story is


00:16:29.839 --> 00:16:32.949
about perhaps one of the most famous um


00:16:32.959 --> 00:16:35.430
celestial objects in the northern sky.


00:16:35.440 --> 00:16:38.389
Uh an object called the ring nebula. Uh


00:16:38.399 --> 00:16:41.030
because it's shaped like a ring. Uh it's


00:16:41.040 --> 00:16:43.350
in the constellation of Lyra. Uh one


00:16:43.360 --> 00:16:45.430
that um certainly I've been aware of


00:16:45.440 --> 00:16:47.350
ever since I first became interested in


00:16:47.360 --> 00:16:49.749
astronomy in the 1950s.


00:16:49.759 --> 00:16:54.069
Um it is a planetary nebula and that is


00:16:54.079 --> 00:16:56.230
a bit of a misnomer term. It was one


00:16:56.240 --> 00:16:57.910
coined by William Hershel in the early


00:16:57.920 --> 00:17:00.629
1800s because these things kind of look


00:17:00.639 --> 00:17:02.150
like planets, but they're nothing to do


00:17:02.160 --> 00:17:03.509
with planets. They're not in the solar


00:17:03.519 --> 00:17:05.669
system. They're clouds of gas. And we


00:17:05.679 --> 00:17:07.429
now know that they are the the bubbles


00:17:07.439 --> 00:17:11.270
of gas that are puffed off by uh uh


00:17:11.280 --> 00:17:14.150
giant stars in their old age. Um and we


00:17:14.160 --> 00:17:16.150
also know that the sun will go through a


00:17:16.160 --> 00:17:17.829
phase where eventually it's surrounded


00:17:17.839 --> 00:17:20.549
by a a nebula, a planetary nebula very


00:17:20.559 --> 00:17:24.630
like the ring nebula. Uh so um we know a


00:17:24.640 --> 00:17:28.150
lot about that nebula and um what's


00:17:28.160 --> 00:17:29.909
there's a sort of slightly personal


00:17:29.919 --> 00:17:32.549
aspect to this story because a uh a


00:17:32.559 --> 00:17:34.630
telescope that I worked on quite


00:17:34.640 --> 00:17:37.430
commonly in the 1990s uh the William


00:17:37.440 --> 00:17:40.310
Hershel telescope uh which uh was then


00:17:40.320 --> 00:17:42.710
operated by the UK I think it's now the


00:17:42.720 --> 00:17:45.909
UK and some other


00:17:45.919 --> 00:17:49.669
uh sorry I'm going to cancel this can't


00:17:49.679 --> 00:17:51.669
take that call don't know whether you


00:17:51.679 --> 00:17:54.150
heard Uh my phone is ringing.


00:17:54.160 --> 00:17:56.950
>> It's ringing in my my earphones. Sorry.


00:17:56.960 --> 00:17:59.350
Yeah. Yeah. Sorry. It's all right. I'll


00:17:59.360 --> 00:18:02.710
call them back shortly. Um it's uh it's


00:18:02.720 --> 00:18:04.230
a


00:18:04.240 --> 00:18:06.950
uh the telescope that uh was built in


00:18:06.960 --> 00:18:10.230
the 19 late 1980s, commissioned I think


00:18:10.240 --> 00:18:13.430
around about 1990. Uh as I said, I


00:18:13.440 --> 00:18:16.390
worked on it in the in the 1990s. A 4.2


00:18:16.400 --> 00:18:19.830
2meter telescope which is situated uh at


00:18:19.840 --> 00:18:23.350
a place called El Rock de los Machos


00:18:23.360 --> 00:18:25.669
which is the name of a peak in the


00:18:25.679 --> 00:18:28.470
island of La Palma. It's a volcanic peak


00:18:28.480 --> 00:18:30.710
uh and there is a major global


00:18:30.720 --> 00:18:34.630
observatory there. Um it's uh it's as I


00:18:34.640 --> 00:18:37.190
said 4.2 m telescope. Uh I think it's


00:18:37.200 --> 00:18:39.590
now jointly operated by a number of uh


00:18:39.600 --> 00:18:41.830
different nations. Uh it was built by


00:18:41.840 --> 00:18:45.590
the Brits uh and uh was for a while


00:18:45.600 --> 00:18:46.870
something like the third biggest


00:18:46.880 --> 00:18:48.870
telescope in the northern hemisphere I


00:18:48.880 --> 00:18:53.110
think. Um it uh uh has an instrument on


00:18:53.120 --> 00:18:55.510
it. Uh which is sort of let me guess.


00:18:55.520 --> 00:18:55.990
Let me guess.


00:18:56.000 --> 00:18:57.110
>> Descendant.


00:18:57.120 --> 00:18:59.270
>> It's a saxophone.


00:18:59.280 --> 00:19:00.150
>> Sorry couldn't help.


00:19:00.160 --> 00:19:03.990
>> It's an E flat trombone. Uh


00:19:04.000 --> 00:19:08.390
it's a it's a um an instrument which is


00:19:08.400 --> 00:19:09.830
I was going to say it's a descendant of


00:19:09.840 --> 00:19:12.390
a let me rephrase that. It is an optical


00:19:12.400 --> 00:19:15.830
instrument. Uh which is a descendant of


00:19:15.840 --> 00:19:17.990
uh something I was very deeply involved


00:19:18.000 --> 00:19:20.230
with when I was there. Um I was project


00:19:20.240 --> 00:19:21.830
scientist for a thing called a


00:19:21.840 --> 00:19:24.950
spectrograph which is um uh the device


00:19:24.960 --> 00:19:27.430
that splits up light uh and lets us see


00:19:27.440 --> 00:19:30.390
that barcode of information in the light


00:19:30.400 --> 00:19:32.470
of a star or galaxy or indeed a


00:19:32.480 --> 00:19:35.029
planetary nebula. Uh but the new version


00:19:35.039 --> 00:19:37.830
of that I we were using optical fibers


00:19:37.840 --> 00:19:40.549
uh to to look at individual objects. uh


00:19:40.559 --> 00:19:43.590
the new version uh uses optical fibers


00:19:43.600 --> 00:19:46.070
again but in such a way that you can


00:19:46.080 --> 00:19:48.870
look at an object like this nebula and


00:19:48.880 --> 00:19:51.110
for every point on the image you can get


00:19:51.120 --> 00:19:54.150
a spectrum uh and we uh it's a a


00:19:54.160 --> 00:19:56.390
technology which is known as integral


00:19:56.400 --> 00:19:58.549
field spectroscopy


00:19:58.559 --> 00:20:00.870
uh and uh they have built something


00:20:00.880 --> 00:20:03.190
called a LEU which is a large integral


00:20:03.200 --> 00:20:06.230
field unit for the weave instrument


00:20:06.240 --> 00:20:10.390
which is the WH enhanced area velocity


00:20:10.400 --> 00:20:13.029
Explorer. Uh, great stuff. And the


00:20:13.039 --> 00:20:15.430
bottom line is that the to get to the


00:20:15.440 --> 00:20:17.990
end of this long rambling story. This is


00:20:18.000 --> 00:20:19.990
a brand new instrument that is just


00:20:20.000 --> 00:20:23.510
being tested. And what better object to


00:20:23.520 --> 00:20:25.669
test it on than this lovely northern


00:20:25.679 --> 00:20:28.390
hemisphere nebula, the Ring Nebula. And


00:20:28.400 --> 00:20:31.029
so that's what they've done. a group of


00:20:31.039 --> 00:20:33.909
scientists mostly I think from the UK uh


00:20:33.919 --> 00:20:35.750
they've used the ring nebula just to


00:20:35.760 --> 00:20:38.070
make sure that the weave spectrograph


00:20:38.080 --> 00:20:40.390
works properly and does everything they


00:20:40.400 --> 00:20:42.549
want it to and they've uncovered a


00:20:42.559 --> 00:20:45.590
complete surprise uh that has blown


00:20:45.600 --> 00:20:47.270
everybody's mind because nobody


00:20:47.280 --> 00:20:49.909
understands it and that is exactly as


00:20:49.919 --> 00:20:52.789
you've said is an iron bar. Now, um,


00:20:52.799 --> 00:20:54.870
when you talk about a bar in astronomy,


00:20:54.880 --> 00:20:56.630
it's not something you prop yourself up


00:20:56.640 --> 00:20:59.190
against to, um, get over all your


00:20:59.200 --> 00:21:01.350
problems. Uh, although you can do that


00:21:01.360 --> 00:21:05.029
if you want. Uh, it's it's uh, usually


00:21:05.039 --> 00:21:06.870
it's a


00:21:06.880 --> 00:21:09.830
a structure, a linear structure. Um,


00:21:09.840 --> 00:21:12.789
often made of stars. Uh, galaxies often


00:21:12.799 --> 00:21:14.390
have a bar across the middle. We call


00:21:14.400 --> 00:21:16.870
them barred spiral galaxies. And that


00:21:16.880 --> 00:21:18.470
bar is made of stars which are


00:21:18.480 --> 00:21:22.310
circulating in a in a very elliptical


00:21:22.320 --> 00:21:24.549
orbit around the center of the galaxy.


00:21:24.559 --> 00:21:27.830
So it looks like a essentially a solid


00:21:27.840 --> 00:21:29.909
bar of material. It's actually made of


00:21:29.919 --> 00:21:32.470
stars. So the bar in the ring ring


00:21:32.480 --> 00:21:34.950
nebula is not made of stars. It's made


00:21:34.960 --> 00:21:38.789
of gas. Uh but what is interesting is


00:21:38.799 --> 00:21:41.350
that that gas is highly ionized. That


00:21:41.360 --> 00:21:45.590
means energized uh version of iron. So


00:21:45.600 --> 00:21:50.149
this is a plasma of iron atoms. Uh and


00:21:50.159 --> 00:21:51.990
um one of the interesting comments that


00:21:52.000 --> 00:21:55.110
comes out of the the data um that's been


00:21:55.120 --> 00:21:58.470
released on this on this uh piece of


00:21:58.480 --> 00:22:00.870
research is that the total mass of the


00:22:00.880 --> 00:22:04.310
iron that's in that bar is comparable to


00:22:04.320 --> 00:22:07.029
the mass of Mars. Uh that is quite


00:22:07.039 --> 00:22:09.669
significant. Uh and I love this comment.


00:22:09.679 --> 00:22:12.470
its length is about equal to 500 times


00:22:12.480 --> 00:22:15.110
the orbit of Pluto around the sun. Uh


00:22:15.120 --> 00:22:17.350
and so it's, you know, if you imagine


00:22:17.360 --> 00:22:19.990
Pluto's orbit, multiply it by 500 times


00:22:20.000 --> 00:22:21.830
and then take its diameter, that's how


00:22:21.840 --> 00:22:24.549
big this iron bar is. Uh so it's not an


00:22:24.559 --> 00:22:26.230
iron bar in the sense that something you


00:22:26.240 --> 00:22:28.149
can pick up and hit somebody on the head


00:22:28.159 --> 00:22:30.549
with if you're that way inclined, and


00:22:30.559 --> 00:22:33.029
I'm certainly not. uh uh but it's an


00:22:33.039 --> 00:22:35.270
iron bar in the sense of a barred


00:22:35.280 --> 00:22:39.430
structure in what is completely normally


00:22:39.440 --> 00:22:41.669
expected to be quite spherically


00:22:41.679 --> 00:22:43.590
symmetrical because this is a bubble of


00:22:43.600 --> 00:22:45.750
material. The ring nebula is a bubble of


00:22:45.760 --> 00:22:48.470
gas and yet here in the middle of it is


00:22:48.480 --> 00:22:51.990
this linear feature a bar uh of made of


00:22:52.000 --> 00:22:55.029
highly ionized iron atoms. So as you


00:22:55.039 --> 00:22:57.430
said at the beginning Andrew the big


00:22:57.440 --> 00:22:59.909
question now is where did it come from?


00:22:59.919 --> 00:23:02.149
>> Yeah. What? Why is it there? What what


00:23:02.159 --> 00:23:04.149
happened to create that? Because it's it


00:23:04.159 --> 00:23:05.990
sounds like it's it's unique. There's


00:23:06.000 --> 00:23:08.549
nothing else like it yet bound.


00:23:08.559 --> 00:23:10.149
>> Not that we know of. That's right. But


00:23:10.159 --> 00:23:12.549
nobody's looked for a lion in Yeah. Uh


00:23:12.559 --> 00:23:16.149
in the center of these these objects. So


00:23:16.159 --> 00:23:21.830
um I think uh there is, you know, a a


00:23:21.840 --> 00:23:25.110
sort of well as the as the article we


00:23:25.120 --> 00:23:27.350
might quote because this is from our old


00:23:27.360 --> 00:23:29.270
friend Universe Today. It's by Evan


00:23:29.280 --> 00:23:36.149
Goff. Uh the um the bottom line is that


00:23:36.159 --> 00:23:38.470
uh there are two uh let me let me let me


00:23:38.480 --> 00:23:40.470
just read because this is uh this is


00:23:40.480 --> 00:23:41.990
quite nicely put. There are two broad


00:23:42.000 --> 00:23:44.149
exploration explanations for this iron


00:23:44.159 --> 00:23:46.390
bar. One is that it reveals something


00:23:46.400 --> 00:23:48.789
new about how the central star and


00:23:48.799 --> 00:23:50.870
that's the star that it eventually gave


00:23:50.880 --> 00:23:53.029
rise to the nebula. How the central star


00:23:53.039 --> 00:23:55.909
ejected its material. Uh the other is


00:23:55.919 --> 00:23:58.390
that the bar, the iron bar is the


00:23:58.400 --> 00:24:01.350
remnant of a planet that was vaporized


00:24:01.360 --> 00:24:03.830
and destroyed by the star as it expanded


00:24:03.840 --> 00:24:06.870
into a red giant. That's a really really


00:24:06.880 --> 00:24:09.270
interesting uh conjecture that what


00:24:09.280 --> 00:24:11.909
we're seeing is perhaps the um the


00:24:11.919 --> 00:24:16.149
remnant that the vaporized core of a


00:24:16.159 --> 00:24:18.310
planet, perhaps a rocky planet that was


00:24:18.320 --> 00:24:20.630
in orbit around the star uh when it


00:24:20.640 --> 00:24:23.110
turned into a red giant. uh it was


00:24:23.120 --> 00:24:25.909
vaporized and what we are left with is


00:24:25.919 --> 00:24:30.630
this streak of uh highly ionized gas uh


00:24:30.640 --> 00:24:33.750
highly energized gas uh made of iron


00:24:33.760 --> 00:24:35.750
across the middle of the nebula. Really


00:24:35.760 --> 00:24:38.149
really interesting uh uh really


00:24:38.159 --> 00:24:40.630
interesting um results there.


00:24:40.640 --> 00:24:42.549
>> Yeah, absolutely. And and the pictures


00:24:42.559 --> 00:24:45.190
that they've gathered are spectacular.


00:24:45.200 --> 00:24:46.149
It looks amazing.


00:24:46.159 --> 00:24:48.950
>> Yeah. Yeah, it does. It's quite


00:24:48.960 --> 00:24:50.950
extraordinary. Uh there's a quote from


00:24:50.960 --> 00:24:54.230
Janet Drew who I won't say I know but


00:24:54.240 --> 00:24:55.750
I'd certainly have met her a few times


00:24:55.760 --> 00:24:57.750
back in the day. Uh she's one of the


00:24:57.760 --> 00:25:00.549
studies co-authors uh University College


00:25:00.559 --> 00:25:03.990
London uh said says we this is in a


00:25:04.000 --> 00:25:06.230
press release we definitely need to know


00:25:06.240 --> 00:25:08.149
more particularly whether any other


00:25:08.159 --> 00:25:10.870
chemical elements coexist with the newly


00:25:10.880 --> 00:25:13.350
detected iron as this would probably


00:25:13.360 --> 00:25:15.269
tell us the right class of model to


00:25:15.279 --> 00:25:18.149
pursue. In other words, um whether it


00:25:18.159 --> 00:25:20.230
was ejected from the star or a vaporized


00:25:20.240 --> 00:25:22.549
planet. Uh right now we're missing this


00:25:22.559 --> 00:25:24.710
important information. So, yep. Really


00:25:24.720 --> 00:25:26.950
um really interesting stuff.


00:25:26.960 --> 00:25:28.789
>> Yeah. And now that they've found it,


00:25:28.799 --> 00:25:30.789
they know what to look for and they may


00:25:30.799 --> 00:25:34.230
well find that this has happened quite a


00:25:34.240 --> 00:25:35.830
few times that you might even have one


00:25:35.840 --> 00:25:38.710
in your closet. You never know.


00:25:38.720 --> 00:25:41.190
What's what uh is interesting to me and


00:25:41.200 --> 00:25:44.230
there's a it's a tenuous link here but


00:25:44.240 --> 00:25:46.549
um perhaps the most famous planetary


00:25:46.559 --> 00:25:48.870
nebula in the southern hemisphere and


00:25:48.880 --> 00:25:50.870
it's one that is very familiar. It's


00:25:50.880 --> 00:25:53.190
called the Helix Nebula. Beautiful.


00:25:53.200 --> 00:25:57.190
Again, a ring-like structure. Uh we just


00:25:57.200 --> 00:25:59.269
uh yesterday I think or the day before


00:25:59.279 --> 00:26:01.590
received some new images of that from


00:26:01.600 --> 00:26:04.310
the James Webb uh space telescope which


00:26:04.320 --> 00:26:07.590
are absolutely staggering. uh they show


00:26:07.600 --> 00:26:10.470
structure on the sort of inner edge of


00:26:10.480 --> 00:26:12.470
this bubble of gas which is what the


00:26:12.480 --> 00:26:16.710
Helix Nebula is as well. Uh which is


00:26:16.720 --> 00:26:19.590
it's it's it's unfathomable almost. What


00:26:19.600 --> 00:26:21.110
we're seeing is little bubbles of gas


00:26:21.120 --> 00:26:23.750
being stretched out into these these


00:26:23.760 --> 00:26:25.269
myriad of fingers. It almost looks like


00:26:25.279 --> 00:26:27.110
a grassy paddock. It is quite


00:26:27.120 --> 00:26:28.789
extraordinary. It's well worth a look if


00:26:28.799 --> 00:26:31.269
you can find it, Andrew. Uh and I


00:26:31.279 --> 00:26:33.350
encourage our listeners and viewers to


00:26:33.360 --> 00:26:35.269
look for the James Webb telescope image


00:26:35.279 --> 00:26:38.310
of the ring of the Helix Nebula uh just


00:26:38.320 --> 00:26:39.350
released.


00:26:39.360 --> 00:26:40.149
>> Yeah.


00:26:40.159 --> 00:26:41.990
>> Keep an eye on that. But if you uh want


00:26:42.000 --> 00:26:44.230
to read about this particular iron bar


00:26:44.240 --> 00:26:48.310
discovery, you can read it uh on what is


00:26:48.320 --> 00:26:50.789
uh the universe today.com website or you


00:26:50.799 --> 00:26:53.430
can go to the paper which was published


00:26:53.440 --> 00:26:55.669
in the


00:26:55.679 --> 00:26:57.830
Royal Astronomical Society monthly


00:26:57.840 --> 00:27:00.630
notices of you could say it the other


00:27:00.640 --> 00:27:02.950
way around and you'd be right. Uh yeah.


00:27:02.960 --> 00:27:04.470
Um,


00:27:04.480 --> 00:27:06.310
but the pictures are spectacular in


00:27:06.320 --> 00:27:08.310
themselves, but the mystery itself is uh


00:27:08.320 --> 00:27:11.750
is quite um quite extraordinary. You're


00:27:11.760 --> 00:27:13.750
listening to Space Nuts with Andrew


00:27:13.760 --> 00:27:19.029
Dunley and Professor Fred Watson.


00:27:19.039 --> 00:27:21.190
>> Okay, we checked all four systems and


00:27:21.200 --> 00:27:21.990
being with


00:27:22.000 --> 00:27:23.350
>> Space Nuts.


00:27:23.360 --> 00:27:27.590
>> Our final yarn, Fred, uh takes us into


00:27:27.600 --> 00:27:30.950
uh a bit of a mystery land. um something


00:27:30.960 --> 00:27:32.950
deadly that could be important in the


00:27:32.960 --> 00:27:35.830
origin of life. Uh and you know if you


00:27:35.840 --> 00:27:38.950
would ask people what is deadly to human


00:27:38.960 --> 00:27:41.750
life and life in general um you would


00:27:41.760 --> 00:27:45.990
come up with a few well-known um things


00:27:46.000 --> 00:27:49.269
including hydrogen cyanide and and that


00:27:49.279 --> 00:27:52.470
is the topic of the discussion.


00:27:52.480 --> 00:27:55.110
>> Yeah, that's right. Um now I pre I


00:27:55.120 --> 00:27:56.870
preface this discussion with something


00:27:56.880 --> 00:27:58.470
that you and all our listeners know


00:27:58.480 --> 00:28:00.789
already and that is that I'm no chemist


00:28:00.799 --> 00:28:04.070
and certainly no um biochemist but um


00:28:04.080 --> 00:28:07.190
this is a yeah it's a really interesting


00:28:07.200 --> 00:28:10.870
uh study um that I think comes from


00:28:10.880 --> 00:28:15.909
Swedish uh Swedish scientists uh and


00:28:15.919 --> 00:28:18.630
it's it's about


00:28:18.640 --> 00:28:22.389
hydro hydrogen cyanide as a molecule HCN


00:28:22.399 --> 00:28:25.190
it's a chemical ical formula um which we


00:28:25.200 --> 00:28:28.630
know occurs uh commonly in space. It's


00:28:28.640 --> 00:28:30.230
one of these molecules that seems to be


00:28:30.240 --> 00:28:33.669
readily formed um in the co uh the


00:28:33.679 --> 00:28:35.990
coldness of space. So we find it for


00:28:36.000 --> 00:28:39.350
example in comets um and that's one of


00:28:39.360 --> 00:28:41.750
the reasons why excuse me there was


00:28:41.760 --> 00:28:44.950
panic in 1910 um when it was known that


00:28:44.960 --> 00:28:47.110
there was hydrogen cyanide in the tail


00:28:47.120 --> 00:28:49.350
of comet Halley and the earth was going


00:28:49.360 --> 00:28:51.990
to pass through the tail and so um I


00:28:52.000 --> 00:28:55.110
think all these quack you know quack


00:28:55.120 --> 00:28:56.630
chemists


00:28:56.640 --> 00:28:59.029
made up their their potions to stop you


00:28:59.039 --> 00:29:01.510
being poisoned by hydrogen cyanide fact


00:29:01.520 --> 00:29:04.549
that it's you know very very rarified


00:29:04.559 --> 00:29:06.789
gas wasn't something that impinged on


00:29:06.799 --> 00:29:08.950
their on their consciousness. They just


00:29:08.960 --> 00:29:11.269
made money out of it. Anyway, it's in


00:29:11.279 --> 00:29:14.470
comets. Uh it's in clouds of


00:29:14.480 --> 00:29:17.350
interstellar gas and dust. Uh it's also


00:29:17.360 --> 00:29:19.909
present in large amounts actually as an


00:29:19.919 --> 00:29:23.029
ice in the atmosphere of Titan, Saturn's


00:29:23.039 --> 00:29:24.310
moon, Titan.


00:29:24.320 --> 00:29:28.389
>> Uh and um it's um not only on the


00:29:28.399 --> 00:29:30.549
atmosphere, but it condenses out on


00:29:30.559 --> 00:29:33.269
deposits onto the surface as well. And


00:29:33.279 --> 00:29:36.230
so the basically the


00:29:36.240 --> 00:29:37.909
>> Don't lick the rocks, kids.


00:29:37.919 --> 00:29:39.350
>> Don't lick the rocks. Don't lick the


00:29:39.360 --> 00:29:39.750
rocks. In


00:29:39.760 --> 00:29:41.350
>> fact, don't and don't breathe the


00:29:41.360 --> 00:29:43.990
atmosphere.


00:29:44.000 --> 00:29:46.070
>> Uh which you wouldn't want to anyway um


00:29:46.080 --> 00:29:48.870
because it's pretty horrible. But um the


00:29:48.880 --> 00:29:52.230
so so that has led scientists to look


00:29:52.240 --> 00:29:56.789
more closely at the chemistry uh and


00:29:56.799 --> 00:30:00.470
sort of physics as well of of hydrogen


00:30:00.480 --> 00:30:03.669
cyanide. And in particular, what they've


00:30:03.679 --> 00:30:07.269
found is that it has essentially


00:30:07.279 --> 00:30:11.190
electric electrostatic properties that


00:30:11.200 --> 00:30:14.470
um may encourage


00:30:14.480 --> 00:30:17.990
uh it to assist with the formation of


00:30:18.000 --> 00:30:20.789
other molecules. It's apparently got


00:30:20.799 --> 00:30:24.789
really strong electric fields at the


00:30:24.799 --> 00:30:28.389
ends of a a solid crystal of hydrogen


00:30:28.399 --> 00:30:31.830
cyanide. Um, and what they're saying is


00:30:31.840 --> 00:30:34.549
that that might be a property that would


00:30:34.559 --> 00:30:38.630
allow this deadly chemical nevertheless


00:30:38.640 --> 00:30:42.310
to assist in the, you know, the the


00:30:42.320 --> 00:30:46.070
building up of uh prebiotic molecules,


00:30:46.080 --> 00:30:49.750
the the organic molecules that we think


00:30:49.760 --> 00:30:53.269
um are basically the uh the building


00:30:53.279 --> 00:30:55.350
blocks of life. M


00:30:55.360 --> 00:30:57.029
>> um


00:30:57.039 --> 00:31:02.149
it's so so it's um yeah it's really uh a


00:31:02.159 --> 00:31:06.149
really interesting uh piece of work that


00:31:06.159 --> 00:31:09.669
they are uh that these these authors


00:31:09.679 --> 00:31:13.269
have highlighted that maybe uh this this


00:31:13.279 --> 00:31:15.750
thing that to us is anathema hydrogen


00:31:15.760 --> 00:31:18.149
cyanoid maybe it's the reason why we're


00:31:18.159 --> 00:31:20.549
here uh because of reactions that might


00:31:20.559 --> 00:31:23.430
have taken place and of course that has


00:31:23.440 --> 00:31:26.950
um some interesting uh implications for


00:31:26.960 --> 00:31:29.590
Titan if it's common place on Titan.


00:31:29.600 --> 00:31:32.549
Titan's a world that we think could


00:31:32.559 --> 00:31:37.110
harbor life uh maybe in its uh under ice


00:31:37.120 --> 00:31:39.190
oceans. It's an ice world like many of


00:31:39.200 --> 00:31:40.950
the other uh satellites of the outer


00:31:40.960 --> 00:31:43.350
planets, but also has these seas and


00:31:43.360 --> 00:31:46.950
lakes of liquid ethane and methane. Um,


00:31:46.960 --> 00:31:48.549
you know, maybe there there are


00:31:48.559 --> 00:31:51.430
reactions going on in there that involve


00:31:51.440 --> 00:31:54.310
hydrogen cyanide that might have created


00:31:54.320 --> 00:31:57.350
uh uh organisms that use these um


00:31:57.360 --> 00:32:00.230
basically these uh liqufied natural


00:32:00.240 --> 00:32:03.029
gases, which is what they are as their


00:32:03.039 --> 00:32:06.070
working fluid. Who knows? Well, and and


00:32:06.080 --> 00:32:07.350
that's something we've talked about


00:32:07.360 --> 00:32:09.830
before because we, you know, when you we


00:32:09.840 --> 00:32:11.750
think of life, we we look at ourselves,


00:32:11.760 --> 00:32:13.750
carbon based life forms that breathe


00:32:13.760 --> 00:32:17.029
oxygen and, you know, and have a heavy


00:32:17.039 --> 00:32:20.549
reliance on water, but why does it just


00:32:20.559 --> 00:32:24.070
have to be that? Why why can't life


00:32:24.080 --> 00:32:26.149
develop in an environment that we would


00:32:26.159 --> 00:32:31.110
find toxic and well, basically hostile?


00:32:31.120 --> 00:32:34.149
But if you can create the catalyst for


00:32:34.159 --> 00:32:36.870
life on a world like Titan, why couldn't


00:32:36.880 --> 00:32:39.750
it develop independently as a a totally


00:32:39.760 --> 00:32:40.789
different life form?


00:32:40.799 --> 00:32:42.230
>> Something quite different. That's right.


00:32:42.240 --> 00:32:43.750
And um you know, that raises the


00:32:43.760 --> 00:32:45.350
question, how do you recognize that it's


00:32:45.360 --> 00:32:48.230
actually life if it's so different from


00:32:48.240 --> 00:32:51.430
from our our living organisms, too?


00:32:51.440 --> 00:32:53.190
>> Well, we don't really have a proper


00:32:53.200 --> 00:32:54.950
definition of what life is.


00:32:54.960 --> 00:32:58.870
>> No. No. And you you know some people


00:32:58.880 --> 00:33:02.630
argue that a virus isn't a life form.


00:33:02.640 --> 00:33:03.350
>> Yeah.


00:33:03.360 --> 00:33:07.669
>> So is is a is a virus life?


00:33:07.679 --> 00:33:09.669
>> I've seen that argument tossed around a


00:33:09.679 --> 00:33:14.310
few times. So what debate rages?


00:33:14.320 --> 00:33:16.149
>> Yeah. A definition that I think NASA


00:33:16.159 --> 00:33:18.630
uses from time to time is a living


00:33:18.640 --> 00:33:22.549
organism is a a self- sustaining,


00:33:22.559 --> 00:33:24.070
selfreplicating


00:33:24.080 --> 00:33:27.830
organism capable of Darwinian evolution.


00:33:27.840 --> 00:33:29.830
And and I actually think a virus would


00:33:29.840 --> 00:33:30.470
satisfy that.


00:33:30.480 --> 00:33:32.070
>> I I think it would.


00:33:32.080 --> 00:33:34.230
>> And it does it fast.


00:33:34.240 --> 00:33:35.750
>> Yeah. And it does. And I think I've got


00:33:35.760 --> 00:33:37.190
one at the moment, which is why I feel


00:33:37.200 --> 00:33:38.310
so crooked these days.


00:33:38.320 --> 00:33:40.149
>> Yeah.


00:33:40.159 --> 00:33:41.909
>> Yeah. They hang on, don't they?


00:33:41.919 --> 00:33:43.590
>> They do. Well, you know that that's


00:33:43.600 --> 00:33:46.070
that's the natural order, isn't it? In


00:33:46.080 --> 00:33:48.710
the the the fight for continuity. That's


00:33:48.720 --> 00:33:50.789
what a virus does.


00:33:50.799 --> 00:33:52.870
>> Yeah. All right. Uh very interesting


00:33:52.880 --> 00:33:56.149
story and uh don't go to the chemist


00:33:56.159 --> 00:33:58.630
asking for hydrogen cyanide because you


00:33:58.640 --> 00:34:00.310
want to, you know, revive your cat or


00:34:00.320 --> 00:34:03.750
something. Don't. It doesn't work


00:34:03.760 --> 00:34:05.830
>> because you know it's got um interesting


00:34:05.840 --> 00:34:07.430
electrical properties. It would be a


00:34:07.440 --> 00:34:08.869
good excuse, wouldn't it?


00:34:08.879 --> 00:34:10.389
>> Oh, yes. Well, we'll sell you some if


00:34:10.399 --> 00:34:11.349
that's the case. Yes.


00:34:11.359 --> 00:34:14.230
>> Yes. Why not? Yeah. I don't think you


00:34:14.240 --> 00:34:16.470
could get it very easily, could you?


00:34:16.480 --> 00:34:18.230
>> I don't know how you'd get I don't want


00:34:18.240 --> 00:34:20.470
any, but I don't know how you get it.


00:34:20.480 --> 00:34:22.550
>> You'd have to go to an illegal arms


00:34:22.560 --> 00:34:25.430
dealer or something, I think. But u Yes.


00:34:25.440 --> 00:34:26.790
>> Anyway, uh if you want to read about


00:34:26.800 --> 00:34:31.030
that, it's uh in the universetoday.com


00:34:31.040 --> 00:34:33.829
website. Uh and I think there's probably


00:34:33.839 --> 00:34:36.149
a paper that I have overlooked where


00:34:36.159 --> 00:34:39.109
it's been published, but um uh or you


00:34:39.119 --> 00:34:43.190
could go to the acs.org org website. Uh,


00:34:43.200 --> 00:34:45.270
ACS Central Science is where you'll find


00:34:45.280 --> 00:34:49.190
the article. Um, we're just about done,


00:34:49.200 --> 00:34:51.990
Fred. Thank you very much.


00:34:52.000 --> 00:34:53.829
>> You're welcome, Andrew. And, uh, thank


00:34:53.839 --> 00:34:56.149
you for having me. Um, as always, it's a


00:34:56.159 --> 00:34:56.869
pleasure.


00:34:56.879 --> 00:34:58.790
>> It It is good fun. We really enjoy


00:34:58.800 --> 00:35:00.470
ourselves and hopefully the audience


00:35:00.480 --> 00:35:01.829
does too. They've been sticking with us


00:35:01.839 --> 00:35:04.069
for a good many years now, which we


00:35:04.079 --> 00:35:06.550
greatly appreciate. And between shows,


00:35:06.560 --> 00:35:07.910
don't forget to visit us on social


00:35:07.920 --> 00:35:10.870
media, Facebook, Instagram. we might pop


00:35:10.880 --> 00:35:13.030
up in other places that I'm unaware of.


00:35:13.040 --> 00:35:15.109
I don't know. We'll have to um we'll


00:35:15.119 --> 00:35:16.790
have to go and lean on an iron bar and


00:35:16.800 --> 00:35:19.829
have a few drinks and figure it out. And


00:35:19.839 --> 00:35:22.950
um on our website, you can also uh look


00:35:22.960 --> 00:35:25.270
around at the shop or the astronomy


00:35:25.280 --> 00:35:26.950
daily news feed if you want to sign up


00:35:26.960 --> 00:35:28.950
for that. There's plenty to do on on the


00:35:28.960 --> 00:35:31.589
website, so check it out. Uh and thanks


00:35:31.599 --> 00:35:32.950
to Hugh in the studio who couldn't be


00:35:32.960 --> 00:35:34.230
with us today. We were talking about the


00:35:34.240 --> 00:35:36.550
weather earlier, Fred. And um I don't


00:35:36.560 --> 00:35:37.990
know if you know this, but Hugh's from


00:35:38.000 --> 00:35:39.349
New Zealand. And so once the temperature


00:35:39.359 --> 00:35:41.990
hits 6°, it's way too hot for him to go


00:35:42.000 --> 00:35:44.470
outside. So that's why he can't be with


00:35:44.480 --> 00:35:46.950
us today. And from me, Andrew Dunley,


00:35:46.960 --> 00:35:48.150
thanks for your company. We'll catch you


00:35:48.160 --> 00:35:50.790
on the next episode of Space Nuts.


00:35:50.800 --> 00:35:51.750
Bye-bye.
