  2. Small and Medium Stars • Nebula • Protostar • Brow Dwarf • Main sequence • Hydrogen fusion • Red Giant • Planetary nebula • White Dwarf • Black Dwarf

  3. Nebula Nebula A nebula is a cloud of gas and dust. A nebula turns into a protostar after an additional amount of gas and dust contract to the original nebula. There are four different kinds of nebulae: diffuse, planertary, protoplanetary, supernova remnants.

  4. Protostar A protostar is a large object that’s forms from the gas of a large molecular cloud in the interstellar medium. A interstellar medium is the dust and gas spread around interstellar space. A protostar will turn in to a main sequence star once it gains enough mass, the temperature rises, and hydrogen starts to fuse. A low mass protostar is smaller than a high mass protostar.

  5. Brown Dwarf A brown dwarf is a wanna’ be star but it doesn't get hot enough it be one. There are different types of brown dwarfs. There is spectral class L, spectral T, and spectral Y. Image found at:http://news.nationalgeographic.com/news/2006/03/images/060323_brown_dwarf_big.jpg

  6. Main Sequence A main sequence is the majority of a stars life. The Sun, Sirius and Alpha Centauri A and B are all main sequence stars. The main sequence happens in the center of a star. http://aspire.cosmic-ray.org/labs/star_life/starlife_sequence.html

  7. Hydrogen fusion It happens in main sequence stars. It’s where hydrogen doubles into helium. It releases a lot of energy when this happens. http://en.wikipedia.org/wiki/File:Deuterium-tritium_fusion.svg

  8. Red giant http://en.wikipedia.org/wiki/Red_giant A red giant is a large star weighs about one-half to ten times as much as the sun. Red giant stars are actually red. Some of the main red stars are Mira , Arcturus and Gamma Crucis .

  9. Helium Fusion Helium fusion happens when the star runs out of hydrogen so it starts fusing helium. Helium turns in to carbon. It needs to be a lot more hotter for it to work. The star runs out of helium faster than hydrogen. IMAGE FROM: http://en.wikipedia.org/wiki/File:Helium_atom_QM.svg

  10. Planetary Nebula A planetary nebula is a nebula that is made up of gas and plasma. Planetary nebula is made up of certain stars when they die. Planetary stars don't last for long, compared to a star, which only lives for tens of thousands of years. http://simple.wikipedia.org/wiki/File:Ngc2392.jpg

  11. White dwarf • A white dwarf is a star. The color of a white dwarf is the same as any other regular star, but just not as bright. A star like the sun will become a white dwarf once it has ran out of fuel. Most white dwarf stars are the same size as Earth, and 100 times smaller than the sun. http://en.wikipedia.org/wiki/File:Sirius_A_and_B_Hubble_photo.jpg

  12. Black Dwarf A black dwarf happens when a white dwarf cools off so much that it has so heat or light. Black dwarfs are a hypothesis, and may not be true. This is the end of the small/medium stars life. http://en.wikipedia.org/wiki/File:Color_icon_black.svg

  13. BIG STARS • Red Supergiant • Supernova • Neutron Star • Black Hole

  14. Red Supergiant • Red supergiants are supergiant stars spectral type K or M. They are the largest type of star, in volume. they are not the largest type in mass. this phase it actually short. some starts may turn in to a blue supergiant, but most turn into a supernova!

  15. Supernova • A supernova is when a star explodes. this happiness when a start total runs out of heat and light. after they cause a burst if light that covers a whole galaxy. after this happens it may turn into a black hole or a neutron star. supernova's are very rare. the last one happened in 1604. Image from: http://en.wikipedia.org/wiki/File:Crab_Nebula.jpg

  16. Neutron Star http://simple.wikipedia.org/wiki/File:Neutron_star_cross_section.jpg A neutron star is a star that is almost made up of completely neutrons. It's very small a dense. They are just the leftovers of a massive star. They rotate very fast. They come in different types. There is Pulsar, and Low Mass X-ray Binaries.

  17. Black Hole a black hole is a whole with very strong gravity. light can't even escape it. scientist didn't even know that they excised until recently. http://simple.wikipedia.org/wiki/File:Black_Hole_Milkyway.jpg
