How long does it take light to reach earth from Betelgeuse?

Betelgeuse is a red supergiant star about 640 light-years from Earth. So light from Betelgeuse takes 640 years to get here. Here's an interesting fact; the star Betelgeuse is probably near the end of its life, and may explode in a supernova explosion any time. Very massive stars like Betelgeuse live fast and die in under 100 million years, and Betelgeuse will probably go supernova within the next 10,000 years. This is like no time at all in cosmic terms, but in terms of a HUMAN lifetime, it probably will NOT happen while we're alive to see it. But it could. In fact, Betelgeuse might have exploded 500 years ago, and we wouldn't know it for another 140 years!
