    well done. congrats on doin some h/w.

    formation of stars, sound kewl, so tell me how it happens(in simple terms of course) :p:
    OK, well...

    You got a really big cloud of space dust called a nebular, and eventually (over a few million years) it forms clumps due to gravity, and these clumps are attracted to each other, so they all clump together to make a Protostar.

    If this has enough mass then the protostar will collapse in on itself (due to gravity) and will compress. Thus gravitational potential energy will be converted to kinetic energy (i.e. heat). It gets hot enough to fuse hydrogen, and this fusion slows the contraction. When the outward expansive pressure balances the gravitational collapse it becomes a Main Sequence star.

    The star stays in its main sequence state for billions of years, until its supply of hydrogen runs out. Then, based on its mass, it can go one of 2 ways.

    i) If the star has a high mass, it will expand hugely to become a massive red giant, followed by a supernova explosion, leaving behind a tiny - but very heavy - neutron star. Very occasionally, this neutron star will collapse even further due to gravity and become a Black Hole. Nothing escapes a black hole, not even light! (Greedy :rolleyes:)

    ii)Again, a red giant is formed, but it has insufficient mass to cause a supernova, so eventually the red giant will form a White Dwarf, which after a few years (1000000000 years to be precise) will stop giving off white light, at which point it becomes a black dwarf. This is the route our Sun will follow.

    You'd better read that Lucas, cos it took me ages! :hmpf: :hmmm:
