  1. Stars http://all-the-ways-things-are.tumblr.com/

  2. Stars • Sphere of hot, glowing gas • Produce own light through nuclear fusion • Come in different sizes and colors

  3. dailygalaxy.com dailygalaxy.com deviantart.net space.com gstatic.com findpk.com Types of stars White dwarf Red giant Brown Dwarf Yellow Dwarf Neutron Stars Black Dwarf

  4. sunandstar.net static.memrise.com Types of stars apod.nasa.gov Orange Dwarf Red Dwarf Red Super giant Blue Giant PREV

  5. dailygalaxy.com dangthatscool.com Red Giant • Lifetime: 0.1 - 2 billion years • Smallest kind of main sequence star. • No hydrogen left • core begins to contract • releases gravitational energy • outer layers cool down • shrink and expand

  6. dailygalaxy.com White Dwarf • Lifetime: 1015- 1025 years • Evolution: dead, cooling • burned-out cores of collapsed stars • Planetary nebula

  7. gstatic.com Brown Dwarf • Lifetime: unknown • Too small to generate heat • hasn't gotten enough mass • Nuclear Fusion • very dim and cool

  8. findpk.com Yellow Dwarf • Lifetime: 4 - 17 billion years • Sun • larger than majority of stars • Yellow dwarfs like the sun are white • AppearsyellowthroughRayleighscattering

  9. space.com Black Dwarf • Lifetime: unknown • Evolution: dead • white dwarf has cooled down • No longer emits light

  10. deviantart.net Neutron Stars • Lifetime: unknown • Evolution: dead, cooling • core collapses • combines electrons with protons to form neutrons • Gravity forces core to become even smaller.

  11. sunandstar.net Orange Dwarf • very common • Lifespan three times longer than yellow dwarfs

  12. sunandstar.net Red Dwarf • most common type of star • Burn their fuel slowly • live a very long time • Not shine as brightly

  13. static.memrise.com Blue Giant • large and compact • burn their fuel quickly • extremely bright • grow larger and explode • Super nova

  14. apod.nasa.gov Red Super Giant • more than 8 to 10 solar masses • Outer hydrogen and helium is inactive. • Below hydrogen fuse to helium. • Next helium fuse to carbon. • core iron • shines extremely bright, short time

  15. TRIVIA: DID YOU KNOW THAT WE ARE ALL MADE OUT OF STARDUST
