S: The life cycle of Spica, an awesome star!
BC: By: Isabel Alvino and Dakota Hintz Mrs. Byrd's class 2011/2012
FC: Spica is very bright and has always stood out from others. She's very smart and kind to everyone. This is Spica's Story | Spica!
1: Spica's story starts when she was born here, in the Nebula! | nebula | A Nebula is a big ball of gas and dust that creates stars.
2: Spica's Birth Certificate! Color: Blue Surface Temperature: 24,000K Luminosity: 760 Type/Class: B Average Radius: 7 solar Main Characteristics: Mainly made of helium, and is a blue giant
3: Spica as a Protostar, a.k.a. a baby! | A Protostar is when the Nebula starts to collapse and one day become a star. Usually what's left of the Nebula will eventually become planets, asteroids, or comets.
4: Next is the Main sequence, which is basically Spica's high school and college years. During these years she burns a lot of hydrogen in her body from doing all different kinds of athletic activities and having fun with her friends. Eventually she will run out of all this hydrogen induced energy and will become filled with helium as she starts to grow old.

7: Next is when Spica becomes older, or a Blue Giant. She doesn't have as much energy anymore so she has to burn helium all the time so she can maintain herself.
8: When a star becomes a White Dwarf they're usually the size of Earth. | She looks happy...
9: Now Spica has come to last part of her life, when she becomes very old, or a White Dwarf. She fights the inner emotions she has about growing old (inner gases of star) and fights with the outer forces of old age affecting her (gravity). Eventually her core is crushed and gravity wins.
11: Now, all that's left of Spica is her Stellar Remnants. | Stellar Remnants are all the gas and dust a star leaves behind after they die. Eventually this gas and dust will be swept back up into a new Nebula to start the cycle all over again.
13: Spica will always be missed she was a great star. Athletic, outgoing, kind, and smart.
