all of the hydrogen at the centre of the star is used up, the stars start to change. The outer layers swell until the star is a lot bigger than before, and it is now a red giant.


 * __WHAT STARS TURN INTO ONCE THEY EXPLODE__**

Stars don't have explosions for an amount of time because the nuclear fusion reactions are taking place in the core of the star. The main sequence mostly involves combining hydrogen to form helium. The energy that these reactions make is enough to support their weight against its own gravity.

As a star runs out of fuel it can expand and will begin to ,make heavier elements such as carbon and iron. Once it finally exhausts all of its fuel it will begin to collapse. It is here that the stars begin to start a different phase.

Stars greater than 1.4 times the weight of the Sun will tend to explode in a supernova sending off most of their mass. The core will remain and like smaller stars this will collapse only this time 'electron degeneracy' will not be enough to support the star's weight against its gravitational collapse and it will continue to shrink until it becomes a tiny, but massive, neutron star held together by ' neutron degeneracy'.

If 'neutron degeneracy' is not enough to resist the star from collapsing it will continue to shrink until the matter is all pressed together into an extremely small, extremely dense point called a 'singularity'. This is the centre of a black hole.
 * __LIFE EXPECTANCY OF A STAR__**

stars a being born a dying all over the universe the biggest stars brightly but only live around ten million years.

a star starts it's life by condensing out of material from a cloud of dust and gas, when the tempereture of the star is not enough,
reactions start ,and hydrogen charges to helium, making a medium glow.
