Its very sad to think about all the aliens living in or around the M82 galaxy. I hope they managed to invent inter-galactic space travel in time to escape to another solar system safely. God bless them.

You mean another galaxy, assuming the supernova would create inhospitable conditions throughout all of M82.

  A supernova is a big explosion, but I don't think it's quite 'galaxy sanitizing' big.

      http://what-if.xkcd.com/73/ http://what-if.xkcd.com/73/ A nearby supernova would definitely be sterilizing to the kind of life found on Earth, and to a lot of other imaginable forms. Of course, "nearby" in astronomical terms is sometimes unintuitive. :-)

  I'm pretty sure that 99% of that galaxy didn't feel a thing. The size of m82 is 40000ly and a largest supernovae will affect( not necessarily destroy stuff ), 3000ly around itself. Relevant: http://en.wikipedia.org/wiki/Near-Earth_supernova http://en.wikipedia.org/wiki/Near-Earth_supernova

It may be sad for any aliens living around the star itself and nearby solar systems. The rest of the galaxy won't feel a thing. This is not the 'Star Trek' movie where, for some weird reason I'll never understand, a supernova was a catastrophic event, for civilizations with FTL travel. If our own sun turned into a supernova (not possible btw), the nearby star wouldn't even see that for about 4 years, best case. And that would be just the radiation, matter would take hundreds, if not thousands of years to get there. So it is not like they wouldn't have any warning. And that's for the closest star.

On the contrary, if you consider that supernovae make our version of life possible, maybe life will happen someday at M82 because of this explosion. We are all supernova dust, after all.
