    • M57: Ring [Planetary] Nebula
  3. Planetary Nebula
    The ejected envelope of a red giant star, spread over a volume roughly the size of our solar system, with a hot central star that is in the process of becoming a white dwarf star

    • M45 The Seven Sisters:
    • Pleiades Star Cluster
    • Taurus
  5. What is a Star Cluster [Star Cloud]?
    What are the 2 types & their properties?
    Groups of stars

    • globular clusters [GC]: 
    • tight groups
    • 100s of 1,000s of very old stars gravitationally bound

    • open clusters: 
    • more loosely clustered
    • generally contain few 100 stars
    • often very young
  6. Image Upload
    • M13 Hercules Globular Cluster: visible to the Naked Eye
    • 25,100 ly
  7. Image Upload
    • COROT-2a Aquila
    • Supernova
    • has a planet in close orbit around it
    • purple glow means it's an X-ray source
    • a very active star
  8. Image Upload
    • Cas A Cassiopeia A:
    • youngest known supernova remnant in the Milky Way galaxy
  9. Image Upload
    • Tycho's Star Cassiopeia:
    • Supernova Remnant
    • Type Ia
    • Shines in Gamma Rays
  10. When Does a Supernova Become a Supernova Remnant [the expanding glowing remains from a supernova]?
    • 1st:
    • measure the total E coming from the explosion and how it declines with time
    • 2nd:
    • track the radiation produced when shock waves generated by the rapidly expanding supernova debris slam into surrounding gas If the light from the explosion dominates, the object is still a supernova 
    • If the light from the collision dominates, it has become a supernova remnant
  11. Supernova
    • Explosive death of a star
    • caused by the sudden onset of nuclear burning in a white dwarf star

  12. Red Dwarfs
    Small, cool faint stars at the lower-right end of the main sequence on the H-R diagram, whose color and size give them their name
  13. Neutron Star
    • A dense stellar remnant produced by the collapse of the core of a massive star as part of a supernova that destroys the rest of the star
    • Typically composed almost entirely of neutrons
    • About 20km in diameter
    • About 1.5 times as massive as the Sun
  14. Binary Star System
    A system in which two stars orbit about their common center of gravity
  15. Open [Star] Cluster
    Loosely bound collection of tens to hundreds of stars, a few parsecs across, generally found in the plane of the Milky Way.
  16. Globular Cluster
    Tightly bound, roughly spherical collection of hundreds of thousands, and sometimes millions, of stars spanning about 100 light years. Globular clusters are distributed in the halos around the Milky Way and other galaxies.
  17. What 2 Star Clusters are in Taurus [The Bull]?
    • Pleiades
