If a star exploded will it still emit light back to earth?

Question

Since light doesn't travels instantly, will a thousand light-year away star that just recently died still emit light back to earth and we're are seeing something that don't exist?

Answer 1

When a star goes supernova, it can emit as much energy as an entire galaxy of billions of stars.

If a star within 50 light years of our system went supernova, we would all die.  The light would be many times brighterthan sunlight, but that would signal your end.

However, we luckily live in a sparse part of the galaxy, with all local stars being quite stable (otherwise, we would not be here to talk about it).

And after supernova, the remnant star still emits light, unless it becomes a black hole (which event is still only theory).  

Look up Oliver Manuel on Google – he has proposed that our sun is in fact a supernova remnant, and has a neutron star at its center.  

Answer 2

yes up to the moment that a star stops sending out light then the picture goses black

Answer 3

What we see is the light from the Star 1,000 ago. The image of the Star will be real, to our mind, but the real Star will no longer exist. It would no exist as we see it now. It might be a neutron or just blew off the outer shell and is a dwarf now.

Answer 4

Yes.

A star a thousand light years away can explode, and we won't see it explode until a thousand years later when the light from the supernova reaches us.
