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.

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

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

>> 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
