FC: The Life cycle of a star By: Shannon Stagliano
1: Dedication | I am dedicating this book to my friends and parents for encouraging me all the time and giving me the education I need to be successful.
2: The Beginning of a star The Latin word for “cloud” is nebula. Nebula's are large clouds of gas or dust. Some types of nebula's glow, while others absorb light and hide stars. Other types of nebula's reflect starlight and produce great images. Spiral galaxies usually contain nebula's but elliptical galaxies contain very few. | The Latin word for “cloud” is nebula.

4: The diagonal pattern on and H-R diagram where most stars, lie is called a main sequence stars. Most of stars lifetime is spent in the main sequence stage. When stars are in the main sequence stage they move up on the H-R diagram to become giants or supergiant. Then become white dwarfs. Also our Sun will stay in the main sequence stage for about another 5 to 10 billion years. Also are own sun is in the main sequence stage. | As a childhood Main-Sequence Star
5: Also star the size of our Sun requires about 50 million years to mature from the beginning of the collapse to adulthood. The red giant stage and super giant stage is the third of the life cycle. Red giants are stars that expand and cools once it uses al of its hydrogen. As the star center shrinks the atmosphere of the star grows very large then cools. | As an adult Giants Supergiants
6: The white dwarf stage is the last stage of a stars life cycle. This star has the same mass as the sun or smaller. A white dwarf is described as a small, hot dim star that is a left over center of an older star. These stars do not have any hydrogen left and can no longer generate energy. White dwarf stars can shine for billions of years before they cool completely. | The end of my life White Dwarf
