3. The beginning of all stars All stars off as nebula. These begins are formed of just cloud and dust that attracts each other. Just like a dust bunny under your bed they cling or stick together forming a larger an larger clump. If this space mass gets to be big enough it can then start its life through beginning a star or baby star called a protostar.

4. Protostars A protostar is the first form of a star. This stage is like the baby stage in a humans life span. Source: http://www.spacetelescope.org/bin/image s.pl?embargo=0&viewtype=standard&sear chtype=freesearch&lang=en&string=huge+ star

5. The stars get enough mass to start fusion. They fuse helium. Most stars in the galaxy are main sequence stars. Doesn't gain enough mass to start fusion. It will stay a brown dwarf forever, it will never be a real star. http://outreach.atnf.csiro.au/education/senior/astrophysics/stellarevolution_m ainsequence.html

6. a occurs when a main sequence star runs out of helium and fuses hydrogen instead. Our sun is a Red Giant. http://en.wikipedia.org/wiki/File:The_sun_in_UV.jpg

7. A red giant stops fusing, forcing the outer layers away. http://en.wikipedia.org/wiki/File:NGC7293_(2004).jpg

8. The leftover core once the star cant fuse anything. http://www.phy.mtu.edu/APOD/ap971102.html http://en.wikipedia.org/wiki/White_dwarf_(disambiguation)

9. A white dwarf after trillions of years that have cooled off and you can no longer see.

11. MASSIVE MAIN SQUENCE Massive main sequence stars run out of supplied hydrogen much fast than a regular or small main sequence stars. Source: http://www.spacetel escope.org/bin/imag es.pl?embargo=0&vi ewtype=standard&se archtype=freesearch &lang=en&string=hu ge+star

12. Red Supergiant At this point the star has run out of hydrogen an starts to fuse helium and carbon. The background of this slide is the supernova that a red supergiant made. http://www.spacetelescope.org/images/archive/topic/n ebula/standard/9

13. Supernova A supernova is went fusion stops and the star collapses. This explosion admits a huge amount of power. This explosion could give off as much energy as the sun in its entire life span. http://www.spacetelescope.org/images/archive /topic/nebula/standard/9

14. Neutron A neutron star is the remaining core of the star. It has a super dense core it can be as small as five miles across in diameter but has a mass of 1.5-2 times the mass of the sun. http://www.spacetelescope.org/images/archive/topic/neb ula/standard/9

15. Black Hole This is when a massive main sequence star that is 25-50 times the sun colapes into what scientists call a black hole. http://www.spacetelescope.org/images/ar chive/topic/nebula/standard/9
