I wonder how they determine that... To predict a supernova you'd essentially have to see into the future, a capability that telescopes do not have. They only see the past, which is what we all see when we look at the sky.

 

So, if it happens at the end of this year, it will be 640 years before it's seen on earth. Don't think I'll stay up late waiting for this one.

 

The telescopes maybe powerful enoungh to see the supernova already or signs it has started.We jus cant see with the naked eye yet.So I guess one could say the telescopes see into the future.

The only information we receive is the light that is constantly coming from stars and the rest of the cosmos. The speed of light is constant in its approach to earth, and is entirely unaffected by whatever method you use to observe it. Think of it this way...pause time for moment and the sky simply becomes an image, albeit a spherical one. It is no different from looking at something on paper. You can effectively enlarge the image you see on the paper, you can't look into it.

The only way a telescope sees things in the future is by being a couple feet closer to the sky than our eyes are

 

CHUM is FUM

 

Telescopes see into the past.

 

They basically just take an educated guess. They gather information from all of the stars and compare all of the temperatures, colors, sizes. Based on data from other supernova's they can calculate that based on the size and temperature of the red giant that it will soon go supernova.
I think that would be pretty damn cool. I hope it does happen cuz that is an extremely rare site. I wonder if that is the some one that may end up shooting a stream of radiation in our direction. That won't be good at all. If that happens you can just kiss life on earth goodbye.

 

It would be way awesome to see something like that in our lifetime. It is just a guess though as you said, so the margin for error here could be millions of years lol.
