Stars

What are Stars?
Stars are clumps of gas particles that come together to form a nuclear fusion object, This fusion helps produce heat and energy which turns some of the gas particles into Plasma which is why stars look the way they do.

This extreme pressure and heat is sustained by the fusion of hydrogen into helium.

How do Stars die?
When the hydrogen in a star runs out, The helium starts fusing with other materials, like carbon.

However, when Helium fuses into iron, It cannot fuse any further, and the star collapses and what is left behind is the core of the star.

Some stars supernova instead of collapsing, which is when the matter of the sun explodes and spreads all around the universe, creating gas clouds which can create new stars and planets.

Examples of Stars

 * Our Own Sun is a starSun.gif
 * Betelgeuse, which is a star expected to supernovae in a couple of million years
 * Proxima Centauri, the closest star to our own star, It is 4.6 light years away.
