FC: My Star Diary By: David Tuchman

1: To my Dad who has helped me all of my life and always will help me.

2: Nebulas | A few planetary nebulas exist in the Milky Way. Is a cloud of dust and gasses. A diffuse nebula happens when there are no stars near. The word originated from Latin. Diffuse nebulas have enough gasses and dust to make 100,000 stars.

3: Main-sequence star | Main sequence stars have +5 absolute magnitude. These stars, if they have more than ten solar masses they go under conversion in the core.They are also called dwarf stars. Main sequence is a distinctive star band. Is second and longest stage.

4: They have an absolute magnitude of -5. They are among the biggest stars. They are 10 to 100 times bigger than the sun. As they are at this stage their core starts to shrink.As this happens my atmosphere starts to grow very large and cools down. | Supergiant stars

5: White dwarf stars | They have a maximum of +10 absolute magnitude. It is some thing that is the same size or smaller than the sun. It is a small hot star that has a left over center of a bigger star. It has no hydrogen left in its entire body; it can no longer generate energy by focusing hydrogen atoms into helium atoms. White dwarfs can shine for billions of years before they completely cool down.
