    • 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.
    • Types of Nebulae Diffuse Nebulae (Star Creation) Star Destructionhttp://hubblesite.org/gallery/album/nebula/pr2005012b/npp/all/
    • Diffuse Nebulae Star CreationEmission NebulaeReflection NebulaeDark Nebulae http://hubblesite.org/gallery/album/nebula/pr2006055a/npp/all/
    • 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.
    • 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.
    • 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
    • M20 The Trifid NebulaEmission Nebula Reflection Dark Nebula Nebulae http://www.caelumobservatory.com/gallery/m20.shtml
    • Nebulae formed by Star Death or Destruction Planetary Nebulae Supernova Remnantshttp://hubblesite.org/gallery/album/nebula/pr2009025f/npp/all/
    • 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/
    • 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/
    • 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/
    • Types of Nebulaediffuse nebulae dark dusty clouds planetary nebulae remnants of exploded stars http://hubblesite.org/gallery/album/nebula/supernova_remnant/pr2007030c/npp/all/
