stars are formed by clouds of dust and moved throughout most galaxies. As the clouds collapse a dense of hot core forms and begins to gather dust and some gas.
Secondly,The collapsing material grows hotter and denser forming a circle shape when the heat and the pressure in the star reaches about 1.8 degrees.Then,when the rest of the clouds of gas and dust either falls onto the star or it gets blown away. The star will get hotter and smaller.
Thirdly,when the star runs out of hydrogen the star will go smaller and when a star moves towards the end of their lives.A star is born in a huge cloud of dust and gas known as a nebula and part of the nebula begins to shrink under the pull of its own gravity.
Finally,many things in the universe stars begin very small and when brighter stars are really old they will burn out faster.

Inconclusion,this is how a star forms.
