Betelgeuse Supernova: Did It Happen?

AI Thread Summary
Determining if Betelgeuse has gone supernova recently is impossible due to its distance of approximately 600 light-years from Earth. Any events occurring now would take 600 years to be observed from our planet, as information cannot travel faster than light. Therefore, even if Betelgeuse exploded this month, we would remain unaware for centuries. The discussion emphasizes the limitations of astronomical observation based on light travel time. Understanding these constraints is crucial for interpreting events in distant stars.

Is there anyway we can determine if Betelgeuse has gone supernova earlier this month? (theoretically speaking)
 
Astronomy news on Phys.org
Nope. Betelgeuse is about 600 light-years away. As no information can arrive faster than the speed of light, anything we know about Betelgeuse is 600 years in the past. If something happenned to it in the past month, we wouldn't know for another 600 years.

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...

Thread 'Our Beautiful Universe - Photos and Videos'

This thread is dedicated to the beauty and awesomeness of our Universe. If you feel like it, please share video clips and photos (or nice animations) of space and objects in space in this thread. Your posts, clips and photos may by all means include scientific information; that does not make it less beautiful to me (n.b. the posts must of course comply with the PF guidelines, i.e. regarding science, only mainstream science is allowed, fringe/pseudoscience is not allowed). n.b. I start this...
