Transcript of "Nebulae"

  1. 1. Nebulaeneb⋅u⋅la nɛbyələ [neb-yuh-luh]noun, plural -lae [li, laɪ] http://hubblesite.org/gallery/album/nebula/pr2002011b/npp/all/ A cloud of interstellar gas and dust.
  2. 2. Types of Nebulae Diffuse Nebulae (Star Creation) Star Destructionhttp://hubblesite.org/gallery/album/nebula/pr2005012b/npp/all/
  3. 3. Diffuse Nebulae Star CreationEmission NebulaeReflection NebulaeDark Nebulae http://hubblesite.org/gallery/album/nebula/pr2006055a/npp/all/
  4. 4. Emission Nebulae M8 The Lagoon Nebula •Emit Light •Mostly Hydrogen •Usually Redhttp://upload.wikimedia.org/wikipedia/commons/2/2f/M8HunterWilson.jpg The Lagoon nebula is about 100 light years across and contains many bright star-forming clusters.
  5. 5. Reflection Nebulae NGC 1999 •Reflect Light • Heavy Elements •Usually Blue http://hubblesite.org/gallery/album/nebula/pr2000010a/npp/all/The central star and the nebula have identical spectrums, which tell us that what we see is truly reflected starlight.
  6. 6. Dark Nebulae The Horsehead Nebula •Absorb Light •Visible when blocking light from stars or bright nebulaehttp://apod.nasa.gov/apod/ap081126.htmlDark nebulae obscure light because they consist of micrometer-sized opaque particles
  7. 7. M20 The Trifid NebulaEmission Nebula Reflection Dark Nebula Nebulae http://www.caelumobservatory.com/gallery/m20.shtml
  8. 8. Nebulae formed by Star Death or Destruction Planetary Nebulae Supernova Remnantshttp://hubblesite.org/gallery/album/nebula/pr2009025f/npp/all/
  9. 9. Planetary Nebulae NGC 6543 Cat’s Eye Nebula Formed from medium-sized starsFirst planetary nebula to be analyzed spectroscopically http://hubblesite.org/gallery/album/nebula/pr2005012t/npp/all/
  10. 10. Supernova Remnants M1 The Crab Nebula Formed from large, high mass stars Occurred in 1054 AD and was visible in the daytime for over two weekshttp://hubblesite.org/gallery/album/nebula/pr2005037a/npp/all/
  11. 11. Planetary Nebulae Supernova Remnants http://hubblesite.org/gallery/album/nebula/pr2003011a/npp/all/ thrust their gas clouds back into space where they mix with diffuse nebulae and are recycled into new stars and planetshttp://hubblesite.org/gallery/album/nebula/supernova_remnant/pr2003020a/npp/all/
  12. 12. Types of Nebulaediffuse nebulae dark dusty clouds planetary nebulae remnants of exploded stars http://hubblesite.org/gallery/album/nebula/supernova_remnant/pr2007030c/npp/all/
  13. 13. Observing Nebulae Hubble Space Telescope (HST) Mid-sized Amateur Telescopehttp://en.wikipedia.org/wiki/File:HST-SM4.jpeg
  14. 14. The Ring Nebula – M57 12.5” Dobsonianhttp://hubblesite.org/gallery/album/nebula/planetary/pr1999001a/npp/all/ Hubble Space Telescope
