  2. IDea A. Individuals with Disabilities Education Act B. Individual Development and Educational Assessment C. International Debate Education Association D. Institutional Diagnostic and Evaluation Activity

  3. Intro to Astronomy diagnostic Will compare this to what you entered in August

  4. Final exam • Monday December 12, 2011 • Online • Mastering Astronomy • 5:30 to 7:30 PM

  5. The final four • The Milky Way Galaxy • Galaxies and Dark Matter • Cosmology • Life in the Universe

  6. The milky way galaxy • What is the size and shape? • Number of stars • Bulge, disk and halo • Orbital motion • How do we know the distances? • What is the mass? • How did it form? • What is in the center? • Where are we?

  7. How big is the milky way galaxy? • 10 kpc or 33 light years • 30 kpc or 100 light years • 100 kpc or 330 light years • 300 kpc or 1000 light years • 1000 kpc or 3300 light years

  8. How many stars are in the milky way? • 100 million • 1 billion • 10 billion • 100 billion • Infinite

  9. Three parts of a galaxy • Emission, secretion, legislation • Photosphere, hemisphere, troposphere • Bulge, halo, disk • Hood, fender, trunk • Core, disk, edge

  10. How fast does the sun travel? • 220 km/s • 525 km/s • 1250 km/s • 2250 km/s • 5500 km/s

  11. How do we measure galactic distances • Radar • Parallax • Supernovae • Variable stars • Quasars

  12. How much mass in the milky way? • 6 x 103 solar masses • 6 x 106solar masses • 6 x 109solar masses • 6 x 1011solar masses • 6 x 1015solar masses

  13. Galaxies form out of…. • Nomadic stars • Black hole boundaries • Massive gas clouds • Stellar farms • Interstellar gas

  14. The center of our galaxy contains a … • Supernova • White dwarf • Planetary nebula • Black hole • Dark matter cloud

  15. Where in the galaxy are we? • Near the edge of the bulge • Near the outer edge of the galaxy • In the disk about half way between the center and edge • Just below the galactic disk near the bulge • Outside the disk but far from the galactic center

  16. Normal and active galaxies • Classification of galaxies • Distances to galaxies • Clusters • Hubble’s law • Active galaxies and quasars

  17. Types of galaxies • Spirals, non-spirals, spherical, non-spherical • Symmetrical, open, closed, flat • Spirals, barred spirals, ellipticals, irregulars • Hubble, Barlow, Shapley, Norton

  18. Our local cluster is part of which supper cluster? • Maganelinic • Polar • Giant • Virgo • Cygnus

  19. Hubble’s law states that the more distant an object is the greater the… • Rotational speed • Mass • Number of stars • Size of the cluster • Redshift

  20. An accretion disk might be found where? • Globular cluster • Open cluster • Planetary nebula • Center of active galaxy • Next to a brown dwarf

  21. Galaxies and Dark Matter • Where is the dark matter • Galaxy collisions • Galaxy formation • Black holes and active galaxies • Universe on a large scale

  22. Why do we think there is dark matter? • High rotational rate of galaxies • It blocks the light from distant galaxies • We can weigh it • It is pushing galaxies apart • It covers black holes

  23. Collisions between galaxies is rare. • True • False

  24. Galaxies can evolve from what process? • Chance encounters • Mergers • Collisions • All of the above

  25. What are Active galaxies? • Those with supermassive black holes • Those with like the milky way • Those that are growing in size • Those that are very luminous • Small but dense galaxies

  26. We know the size of the universe from… • Radar images • Pulsar star maps • Quasar maps • Cluster and void maps • Redshift surveys

  27. Cosmology • Cosmological principle • Big Bang • Geometry of space • Fate of the universe • History of the universe

  28. The universe seems to have no edge or… • Age • Center • Color • Geometry • Sense of humor

  29. The big bang theory is supported by … • CBS • CMB • CLS • CIA • CPR

  30. The universe is thought to be … • Flat • Open • Closed • Infinite

  31. We think the universe will do what? • Continue to get larger • Collapse • Slow down just enough to stay the same size for the rest of time • Expand and collapse over and over

  32. Looking at distant galaxies is like … • Looking forward in time billions of years • Looking backward in time billions of years

  33. Life in the universe • Cosmic evolution • What is life • Local hosts • Distant hosts • SETI

  34. Which came first in cosmic evolution? • Galactic • Planetary • Biological • Chemical • Particulate
