  1. “Twinkle, Twinkle Little Star” The Life Cycle of a Star: Nursery to Neverland http://www.writedesignonline.com/ Courtney Mutschler Geospace 355

  3. How I Wonder What You Are… • Space acts as a nursery full of the stuff needed to give birth to stars.. • Gas • Dust The Space Nursery provides both these materials in the clouds in the atmosphere of space!

  4. Birth : Protostar Stars are born when gravity pulls in the gas and dust in my Solar Nursery and begins to Shine! When the cool masses of dust and gas combine, a star has a temperature of 1,800,000 degrees F! http://www.virginmedia.com/images/

  5. Way Above the World So High… • The Life Span of a star depends on the type of star it is: • Giant blue Stars = 1 to 100 million years • Yellow Star (the Sun) = 10 billion years • Red dwarf Stars = 100 billion – 1 trillion years

  6. Like a Diamond in the Sky… Giant Red Star During the stars “old age,” the star swells into a giant red star as its hydrogen fuses into helium and burns other fuels. http://upload.wikimedia.org/wikipedia/commons/7/7f/Betelgeuse_star_(Hubble).jpg

  7. RIP Little Twinkle… A star has 3 types of death’s it could face, depending on its size…

  8. White Dwarf: Nuclear energy gone  contractions 1. Small and Medium Stars Black Dwarf: burned out white dwarf (lump of coal) www.williamsclass.com/.../StellarEvolution.htm library.thinkquest.org/.../blackdwarfs.html

  9. 2. Large Blue Star Supernova – a gigantic star explosion, blasting away the stars outer shell, seen by us as a planetary nebula, while the core forms a Neutron Star aka ‘Pulsar’ Star; a result of a gravitational collapse of a star after the outer shell has been blasted away. www.megcabot.com flickr.com

  10. 3. Massive Blue Stars Black Hole: where the gravitational pull is so powerful nothing can escape its one-way surface!
