hi FD if the stars are to live forever then whats gone wrong. this is an actual picture (the crab nebula) of an exploded star. this star is no longer and this is the reminants of the star being flung into interstellar space (as i described in an earlier post about enrichment).the colours are true and ech colour is an element red is hydrogen, blue/green is oxygen. i could post 100s more of simular pictures but this one is the best, as this one was seen to explode by the chineese 1000 years ago. our sun will not go the same way as its to small, instead it will expand engulfing the inner planets, roasting them to a blackened life less cinder.
