which one?
i said it wrong, i ment 4 lightyears(dylexia) and it is proxima centauri, part of the alpha centauri(constellation).
also, a nice thingy i found on the internet is this: htwins.net

really jelle we are not scolars on the subject but do you have to get critical over the sun is a star thing ...i may just have opened a pool and not want to swim
anyway just a cool referance i heard before: if you counted all of the grains of sand on earth it would egual 1% of the stars in the universe.now that is mind boggling

In any case.. The 1% I think is a little behind current knowledge. I think it is more in the order of 0,3% nowadays. And what is really mind boggling.. If you take a sip of water, you are drinking more water molecules than there are stars..

Fortunately I am not a specialist. But I'd swear that light cannot be emitted from a black hole. Black holes are black because light cannot escape from them. But then again; Appearently I am too critical when reading these things. Guess that comes from being an academic.
