    • M1: Crab Nebula
    • Neutron Star
    • Taurus
    • 6,500 ly
    • M57: Ring [Planetary] Nebula
  1. 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
  2. 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
    • M13 Hercules Globular Cluster: visible to the Naked Eye
    • 25,100 ly
    • 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
    • Cas A Cassiopeia A:
    • youngest known supernova remnant in the Milky Way galaxy
    • Tycho's Star Cassiopeia:
    • Supernova Remnant
    • Type Ia
    • Shines in Gamma Rays
  3. 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
  4. Supernova
    • Explosive death of a star
    • caused by the sudden onset of nuclear burning in a white dwarf star

  5. 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
  6. 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
  7. Binary Star System
    A system in which two stars orbit about their common center of gravity
  8. 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.
  9. 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.
  10. What 2 Star Clusters are in Taurus [The Bull]?
    • Pleiades
    • Hyades
  11. M13 Hyades Hercules
  12. What is the Great Globular Cluster?
    nickname for M13 in Hercules
    • M42 Orion:
    • The Orion Nebula
    • South of Orion's belt
    • Closest region of massive star formation to Earth
    • HLTau:
    • youngest planet ever observed being born
  13. SN1993J
  14. Gliese 581
  15. Wolf Rayet Star
  16. Gamma Velorum
  17. NGC 281 Pac Man
  18. NGC7000 North American Nebula
  19. 30 Doradus The Tarantula Nebula
  20. NGC 7293 The Helix Nebula
  21. g359.23-0.82 The Mouse 
  22. SS433 mini Quasar
  23. Cygnus X-1
  24. SGR A
