Glitching Neutron Star Mysteries & SpaceX Launch Countdown: Astronomy Discoveries of the Day | S02E22

Welcome to our Wednesday edition of the Astronomy Daily podcast, where we cover one exciting story each from host Tim Gibbs and AI assistant Hallie. **1. Hallie's Story: A Glitching Neutron Star** Halle discusses the discovery of a neutron star, SGR 1935+2154, that displayed a "glitch" after obliterating an asteroid. This "glitch" involved a change in the star's rotational speed while simultaneously releasing a powerful radio wave blast, a fast radio burst (FRB). This study has enabled astronomers to connect the mysterious radio energy bursts to magnetars, an extreme type of neutron star. These celestial objects are born from the remnant cores of massive stars after they undergo supernovas. With masses equivalent to the sun squeezed into city-sized volumes, magnetars possess the universe's most powerful magnetic fields. **2. SpaceX Launch Update** Our discussion then shifts to a SpaceX launch this week that was called off with just 5 seconds remaining on the countdown clock. The planned launch involved a Falcon 9 rocket topped with 54 Starlink satellites from Florida's Cape Canaveral Space Force Station. While the specific issue causing the delay wasn't disclosed during the webcast, SpaceX assured that both the rocket and satellites were in good health, with plans to try for a launch again soon. **3. Wrapping Up** The podcast ends with Tim reminding you to catch his and Steve's full shows on Fridays and Mondays, respectively. You can download all episodes from SpaceNuts.io or Bitesz.com. **4. Upcoming** SpaceX is targeting Wednesday, July 19 for the next lift-off, meaning a potential 24-hour delay. This could mean a launch Wednesday night, California time, or early Thursday morning, July 20. Thank you for tuning in to Astronomy Daily! We'll see you next time.

00:00:00.200 --> 00:00:05.519
Good aready, and welcome to Astronomy
Daily for Wednesday, the nineteenth of July
2
00:00:05.599 --> 00:00:09.279
twenty twenty three. My name is
Tim Gibson. I will be your host
3
00:00:09.359 --> 00:00:13.480
for today. As usual. I
have Hallie, my AI assistant in the
4
00:00:13.519 --> 00:00:18.839
studio with me and we are going
to do a one story Wednesday, one
5
00:00:18.879 --> 00:00:22.600
story from Hallie in one story from
me. So over to you Hallie for
6
00:00:22.800 --> 00:00:33.439
your story of today. Hi,
Tim, here's my story for today.
7
00:00:34.560 --> 00:00:39.880
Scientists discover glitched a neutron star that
obliterated an asteroid then fired off a brilliant
8
00:00:39.880 --> 00:00:45.280
explosion. The powerful magnetic star blasted
out a fast radio burst and changed its
9
00:00:45.359 --> 00:00:50.399
rotational speed as it ripped apart the
space rock. A rapidly spinning neutron star
10
00:00:50.520 --> 00:00:55.079
with an incredibly powerful magnetic field glitched
when it destroyed a space rock. A
11
00:00:55.159 --> 00:01:00.359
new study suggests the neutron star SGR
nineteen thirty five plus twenty one fifty four,
12
00:01:00.600 --> 00:01:04.280
which is located and estimated thirty thousand
light years away near the center of
13
00:01:04.280 --> 00:01:08.680
the Milky Way, appeared to a
glitch by very briefly changing its rational speed
14
00:01:08.760 --> 00:01:14.120
after an asteroid was pulled in by
its gravity and ripped apart. The glitch
15
00:01:14.159 --> 00:01:18.799
consisted of the star changing its rotational
speed while also releasing a fast radio burst
16
00:01:19.000 --> 00:01:23.680
FRB, a powerful blast of radio
waves. In a new study of that
17
00:01:23.760 --> 00:01:27.719
a glitched of star, astronomers can
finally connect these mysterious bursts of radio energy
18
00:01:27.799 --> 00:01:34.599
to these extreme star corpses known as
magnetars. Like all neutron stars, magnetars
19
00:01:34.640 --> 00:01:38.400
are born when a massive star runs
out of fuel for nuclear fusion, a
20
00:01:38.480 --> 00:01:42.799
process that creates the outward energy needed
to stop a star from collapsing under its
21
00:01:42.799 --> 00:01:46.879
own gravity. As the outer layers
of the star are blown apart by a
22
00:01:46.920 --> 00:01:51.959
powerful supernova or star explosion, the
inner core collapses, berthing a stellar remnant
23
00:01:51.959 --> 00:01:55.560
with the mass of the Sun squeezed
into a width equivalent to the average city
24
00:01:55.560 --> 00:02:00.560
on Earth one teaspoon of neutron star
matter brought to Earth with their way one
25
00:02:00.599 --> 00:02:05.959
billion tons. The collapse also pushes
together the magnetic field lines of the dying
26
00:02:06.040 --> 00:02:10.560
star, creating the universe's most powerful
magnetic fields. Hence, this type of
27
00:02:10.599 --> 00:02:15.759
neutron star boasting a powerful magnetic field
is known as a magnetar. The Astronomy
28
00:02:15.840 --> 00:02:21.280
Daily podcast Thanks for that, Hallie, and now here is a story from
29
00:02:21.280 --> 00:02:28.240
me SpaceX aborts a Starlink satellite launch
with five seconds left in countdown. This
30
00:02:28.360 --> 00:02:30.680
was the second abort for SpaceX in
less than a week. One of the
31
00:02:30.719 --> 00:02:38.599
company's falconine rockets, which were scheduled
to launch fifteen Starlink Internet satellites from California's
32
00:02:38.599 --> 00:02:46.039
Foggy Vandenburg Space for Space on Wednesday, July nineteenth at twelve sorry at one
33
00:02:46.199 --> 00:02:52.240
twenty five am local time, but
it wasn't to be. The launch team
34
00:02:52.319 --> 00:02:59.159
called off things just with five seconds
left on the countdown clock. There are
35
00:02:59.199 --> 00:03:02.199
thousands of launch can go wrong and
only one way that it can go right.
36
00:03:02.599 --> 00:03:07.560
SpaceX Zach Lupin said during the webcast
of the planned launch, given that
37
00:03:08.000 --> 00:03:13.719
we are overtly curious on the ground, and if the team or the vehicle
38
00:03:13.960 --> 00:03:19.080
scene sees anything that just looks even
slightly off, they'll stop the countdown.
39
00:03:19.759 --> 00:03:24.680
SpaceX Atticus Vanderra uttered very similar words. On July fourteenth, after the launch
40
00:03:24.759 --> 00:03:30.960
team called off the planned liftoff of
a Falcon nine topped with fifty four Starlink
41
00:03:30.000 --> 00:03:36.719
satellites from Florida's Cape Canaveral Space Force
Station. That rocket flew without incident.
42
00:03:36.759 --> 00:03:44.240
The following day, acing its record
tying sixteenth mission. It's unclear at this
43
00:03:44.280 --> 00:03:49.280
point what caused Wednesday's aboard. The
mission team did not specify the issue during
44
00:03:49.280 --> 00:03:53.520
the webcast, which ended shortly after
the launch was scrubbed. The weather was
45
00:03:53.719 --> 00:03:59.400
good enough for the launch, despite
the despite the thick. The thick flog
46
00:03:59.439 --> 00:04:03.719
at Vanderby Lupin said that the rocket
and the split stylink saturits are in good
47
00:04:03.759 --> 00:04:11.960
health as SpaceX aims to launch again
soon. The company said on via its
48
00:04:12.000 --> 00:04:16.120
Twitter account that it's targeting Wednesday,
July the nineteenth for the next liftoff.
49
00:04:16.199 --> 00:04:21.199
Presumably that means a twenty four hour
delay with a launch Wednesday night, California
50
00:04:21.279 --> 00:04:27.399
time, which is early Thursday morning, July the twentieth. They Astronomy Daily
