Is it safe to say that when we look at anything through hubble that is 
60,00 (or any given disttance)light years away that we are really not 
looking at what is going on now but instead what was going on a long time 
ago. Now I am 99.9% sure that that is right because it takes so long for 
light to reach us from so far away. What my question is is there any way 
to calculate what a nebula or supernovae are doing currently when we get 
this old image given what we know about them?
