Posted by Ethan on April 17, 2008 Ahh, stars. Giant furnaces of nuclear fusion. Doing the stuff our Sun does, burning hydrogen fuel into helium (among other things) and emitting lots of visible light and energy in the process. But when we take a look at brown dwarfs, they aren’t like normal (i.e., main sequence) stars like our Sun. Instead of burning…
Do all Stars Eventually Explode?
Posted by Ethan on April 7, 2008 What’s going to happen to all the stars in the Universe as they get older? Well, just as nothing can live forever, stars can’t live forever also. Why?
