*Stars*


 * Stars are made from a __hydrogen cloud__.This is called A __nebula__.


 * Next the cloud develops in to a __baby star.__This is called a __Protostar.__




 * A few million years later, the __protostar has developed__ more so it is now called a __star.__


 * After another few million years the star __swells up__,now the star is called a __Red Giant.__




 * The layers of the Red Giant start drifting in to space.This is called a __White Dwarf.__




 * Eventually the star dies.

__High Mass Star__ > > > >
 * High mass stars are made the same way as low mass stars.They start as a cloud of hydrogen.(__nebula)__
 * Next the nebula develops in to a young star.We call this a __protostar.__
 * The protostar grows in to a star.[[image:http://www.le.ac.uk/physics/faulkes/web/images/stars.jpg width="233" height="161" align="left"]]
 * The star swells up in to a __red giant__.
 * The Red giant now either develops in to a __Black hole__ Or a __neutron star.[[image:http://tbn0.google.com/images?q=tbn:NasH90iQBFR9mM:http://www.lancs.ac.uk/ug/hilditch/pic3.gif width="209" height="157" align="left" link="http://images.google.co.uk/imgres?imgurl=http://www.lancs.ac.uk/ug/hilditch/pic3.gif&imgrefurl=http://www.lancs.ac.uk/ug/hilditch/low-mass.html&h=415&w=450&sz=114&hl=en&start=3&tbnid=NasH90iQBFR9mM:&tbnh=117&tbnw=127&prev=/images%3Fq%3Dred%2Bgiant%26gbv%3D2%26svnum%3D10%26hl%3Den"]]__
