The Life Cycle of Stars

Hello I am back and now I am going to be talking about the life cycle of star. In my last blog I told what a star was and how it works. This time I am going to tell you their cycle of how they live.

First of all a star is formed by a big cloud of gas. This cloud of gas is made out of hydrogen and heleium. The cloud of gas and dust becomes more dense over some years. Then the cloud collapses and turns into a star  Some stars that already died can create another star.

Our Sun is a main-sequnce star. That means that the sun is yellow or orange. Also when it dies it will turn into a red giant and implode into a white dwarf. A main-sequence star is a yellow dwarf.

Supernova
A supernova is what happens when a star dies. Supernovas rarely happen. When a red giant explodes it turns into gas and dust. That is what we call a supernova. Our sun would not become a supernova because it is a yellow dwarf. 

Would our sun be a black hole?
Our sun would not become a black hole it will become a white dwarf.
