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

Good aready, and welcome to Astronomy Daily for Wednesday, the nineteenth of July
twenty twenty three. My name is Tim Gibson. I will be your host
for today. As usual. I have Hallie, my AI assistant in the
studio with me and we are going to do a one story Wednesday, one
story from Hallie in one story from me. So over to you Hallie for
your story of today. Hi, Tim, here's my story for today.
Scientists discover glitched a neutron star that obliterated an asteroid then fired off a brilliant
explosion. The powerful magnetic star blasted out a fast radio burst and changed its
rotational speed as it ripped apart the space rock. A rapidly spinning neutron star
with an incredibly powerful magnetic field glitched when it destroyed a space rock. A
new study suggests the neutron star SGR nineteen thirty five plus twenty one fifty four,
which is located and estimated thirty thousand light years away near the center of
the Milky Way, appeared to a glitch by very briefly changing its rational speed
after an asteroid was pulled in by its gravity and ripped apart. The glitch
consisted of the star changing its rotational speed while also releasing a fast radio burst
FRB, a powerful blast of radio waves. In a new study of that
a glitched of star, astronomers can finally connect these mysterious bursts of radio energy
to these extreme star corpses known as magnetars. Like all neutron stars, magnetars
are born when a massive star runs out of fuel for nuclear fusion, a
process that creates the outward energy needed to stop a star from collapsing under its
own gravity. As the outer layers of the star are blown apart by a
powerful supernova or star explosion, the inner core collapses, berthing a stellar remnant
with the mass of the Sun squeezed into a width equivalent to the average city
on Earth one teaspoon of neutron star matter brought to Earth with their way one
billion tons. The collapse also pushes together the magnetic field lines of the dying
star, creating the universe's most powerful magnetic fields. Hence, this type of
neutron star boasting a powerful magnetic field is known as a magnetar. The Astronomy
Daily podcast Thanks for that, Hallie, and now here is a story from
me SpaceX aborts a Starlink satellite launch with five seconds left in countdown. This
was the second abort for SpaceX in less than a week. One of the
company's falconine rockets, which were scheduled to launch fifteen Starlink Internet satellites from California's
Foggy Vandenburg Space for Space on Wednesday, July nineteenth at twelve sorry at one
twenty five am local time, but it wasn't to be. The launch team
called off things just with five seconds left on the countdown clock. There are
thousands of launch can go wrong and only one way that it can go right.
SpaceX Zach Lupin said during the webcast of the planned launch, given that
we are overtly curious on the ground, and if the team or the vehicle
scene sees anything that just looks even slightly off, they'll stop the countdown.
SpaceX Atticus Vanderra uttered very similar words. On July fourteenth, after the launch
team called off the planned liftoff of a Falcon nine topped with fifty four Starlink
satellites from Florida's Cape Canaveral Space Force Station. That rocket flew without incident.
The following day, acing its record tying sixteenth mission. It's unclear at this
point what caused Wednesday's aboard. The mission team did not specify the issue during
the webcast, which ended shortly after the launch was scrubbed. The weather was
good enough for the launch, despite the despite the thick. The thick flog
at Vanderby Lupin said that the rocket and the split stylink saturits are in good
health as SpaceX aims to launch again soon. The company said on via its
Twitter account that it's targeting Wednesday, July the nineteenth for the next liftoff.
Presumably that means a twenty four hour delay with a launch Wednesday night, California
time, which is early Thursday morning, July the twentieth. They Astronomy Daily
