Has There Been a Recent Supernova in Andromeda?

AI Thread Summary
The discussion centers on the frequency of supernovas, noting that our galaxy experiences about one every century. Participants question whether a supernova has occurred in the Andromeda Galaxy in the last 200 years, referencing the historical significance of supernova events like SN1987A. There is frustration expressed over missed opportunities for observation due to timing, particularly regarding advancements in technology. The conversation highlights a desire for future supernova events to coincide with improved observational capabilities. Overall, the topic underscores the ongoing interest in supernova occurrences and their implications for astronomical research.

Wow that sucker reached magnitude 6...
 
Yup, and it's really annoying that it didn't go off ten years later when we would have had photographic plates.

On the other hand, I know more than a few people that were annoyed that SN1987A went off when it did rather than a decade later when Super-Kamiokande was in operation.

I'm going to be annoyed with Betelgeuse when it goes supernova 10 years after I die. :smile:
 

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...
