FC: Star The birth, life, and death of a star. By: Neha Jog
1: Neha, thank you for believing and being awesome the whole way through.
2: A star starts it's life cycle when another star blows up. Lots of gas and dust is left behind. Gravity pulls the dust a gas into a sphere. As the sphere becomes denser, it becomes hotter and the hydrogen changes to helium in a process called nuclear fusion. When it dies all this gas and dust will come together to make a new star.
3: Next on a star's life cycle is being a main sequence star. This is the longest stage of a star. During this stage energy is generated in the core of a star as hydrogen converts into helium. This produces a giant amount of energy. The size of this star won't change in this stage, as long as the star has a lot of hydrogen.
4: At the third stage a star becomes a red giant. A red giant is a type of star that expands and cools once it uses all of it's hydrogen. Eventually the loss of hydrogen causes the core to shrink. As the core shrinks, the atmosphere of the star grows very big and cools to form a red giant. Red giants can be 10 times or bigger than the sun. Super giants can be 100 times bigger than the sun.
5: The last stage of a star's life is being a white dwarf. A white dwarf can be the same size as the sun or smaller. It is a small, hot, star that is the leftover core of a red giant. A white Dwarf has no hydrogen and can't make energy. They can shine for a very long time before the light runs out and it finishes it's life as a cold dark star.

8: Reflection While doing this Mixbook project I learned a lot of things. The first thing I learned was a lot about stars. Before this project I didn't know what a main sequence star was. But now I have learned many things about stars. The second thing I learned was that a star actually has a life cycle. I didn't know that before! The third thing I learned was that I might want to be an astronomer one day. Who knows? And the last thing I learned was how to use Mixbook. That could help me one day if I wanted to make something! Overall this project taught me a lot of things.
