Betelgeuse, which is part of the Orion constellation 640 light years away from Earth, is a red supergiant, meaning that it is nearing the end of its life and is due to explode.

Of course, the conversion from stellar to human terms is pretty extreme, as Betelgeuse is predicted to explode anytime in the next million years.

So don't count on getting a lot of sleep when Betelgeuse explodes, because the only sensible thing for the world to do will be to throw a weeks-long global supernova party.
