Presentation Transcript

  1. Nebula • A cloud of gas and dust; the first stage in a stars life (where stars are “born”) en.wikipedia.org/wiki/Image:Orion_Nebula_-_Hubble_2006

  2. Protostar • A star during its first contraction (a “baby” star). http://www.celestiamotherlode.net/catalog/images/screenshots/fictional/protostar

  3. Main Sequence • A middle-aged stable star (like our sun) http://cse.ssl.berkeley.edu/bmendez/ay10/2002/notes/pics/bt2lf1510_a.jpg

  4. Red Giant • A large, bright cool star http://www-astronomy.mps.ohio-state.edu/~pogge/Ast162/Unit2/Images/rsgstar.gif

  5. White Dwarf • A small, dim, hot star

  6. Black Dwarf • Burnt out white dwarf • When a white dwarf stops giving off light and there is no gas left to burn. • Cold and dark. library.thinkquest.org

  7. Neutron Star • Collapsed dense core of a star that was more massive than our sun. • Mass is up to 3 times the sun with a radius of 10 km. • Has only neutrons. http://filer.case.edu/~sjr16/media/stars_neutron_diagram.jpg

  8. Black Hole • A collapsed star so dense that light cannot escape its gravitational pull (it cannot be seen). • The end stage of an extremely large star. http://filer.case.edu/sjr16/media/stars_blackhole_anatomy.jpg www.bbc.co.uk/derby/unexplained/images/black_hole_270.jpg

  9. Nova • A sudden brightening of a dwarf star. http://www.bbc.co.uk/norfolk/kids/astronomy/nova_270.jpg

  10. Supernova • A massive explosion in which the outer layers of a massive star are blown away. • This creates elements heavier than iron. http://www.sacredground.cc/super%20nova%20cassiopeia.jpg

  11. Quasar • A very bright “star like”, distant object in space used to support the Big Bang. • Very bright, very old http://outreach.jach.hawaii.edu/pressroom/2003_distantquasar/quasar_simonnet.jpg

  12. Pulsar • A rapidly spinning neutron star which sends out pulses of radio waves hep.ph.liv.ac.uk

  13. Variable Star • A red giant star which expands and contracts over time. It varies in temperature, brightness and size, because of inward pull of gravity/ outward force of fusion courses.nnu.edu/ph106wj/images/Variable_star.jpg http://helios.augustana.edu/science/img-APOD/variable-star-v838-mon-300.jpg
