AI Thread Summary
The nearest supernova candidate to Earth is HR8210, also known as IK Pegasi, located approximately 150 light-years away. Discovered in the 1990s, it has recently been classified as a type-1 supernova candidate, raising concerns about its potential impact if it were to explode. Users are encouraged to utilize online tools like the Alcyone Star Information Tool and Fourmilab's YourSky Virtual Telescope to locate HR8210 in the sky. The discussion highlights the lack of readily available location information for HR8210, prompting users to seek additional resources. Understanding the proximity and classification of HR8210 is crucial for assessing potential risks associated with supernova events.

What is the nearest supernova candidate (maybe Betelguese?) to the Earth?
 
Astronomy news on Phys.org
That would be HR8210, discovered sometime in the 90's, but only recently recognised as a type-1 supernova candidate. It's only about 150 ly away, and be the end of us if it went off now.

Where is HR8210 located in the sky? It's amazing that a simple search under HR8210 doesn't bring up anything with a location. Thanks.
 
(something else now to lay awake nights dreading) :eek:

Mike2,

HR8210 is IK Pegasi.

link to Alcyone Star Information Tool --->
http://www.alcyone.de/SIT/

point to 'click for a single star', then click.
enter 8210 in 'enter HR number' box, then click

(
more directly --->

)

point to one of the catalogue names along the left and click

use this information to locate on Fourmilab YourSky Virtual Telescope --->
http://www.fourmilab.ch/yoursky/

for example: 21h 24m 7s for Right Ascension, 19°9'29" for Declination , click North 'yes'
point to 'Aim Virtual Telescope' and click

Thread 'Potential biosignature found in Mars rock'

Publication: Redox-driven mineral and organic associations in Jezero Crater, Mars Article: NASA Says Mars Rover Discovered Potential Biosignature Last Year Press conference The ~100 authors don't find a good way this could have formed without life, but also can't rule it out. Now that they have shared their findings with the larger community someone else might find an explanation - or maybe it was actually made by life.

Thread 'Does it make sense to build new radio telescopes?'

TL;DR Summary: In 3 years, the Square Kilometre Array (SKA) telescope (or rather, a system of telescopes) should be put into operation. In case of failure to detect alien signals, it will further expand the radius of the so-called silence (or rather, radio silence) of the Universe. Is there any sense in this or is blissful ignorance better? In 3 years, the Square Kilometre Array (SKA) telescope (or rather, a system of telescopes) should be put into operation.

Thread 'Could gamma-ray bursts have an intragalactic origin?'

Thread 'Could gamma-ray bursts have an intragalactic origin?'

This is indirectly evidenced by a map of the distribution of gamma-ray bursts in the night sky, made in the form of an elongated globe. And also the weakening of gamma radiation by the disk and the center of the Milky Way, which leads to anisotropy in the possibilities of observing gamma-ray bursts. My line of reasoning is as follows: 1. Gamma radiation should be absorbed to some extent by dust and other components of the interstellar medium. As a result, with an extragalactic origin, fewer...
