Welcome to Vol 7 Astronomy!

This whole unit is worth a total of 40 points. This unit's 38 questions can be answered by using the links provided above the different sets of questions. You are only required to get a total of 10 points each day, for a total of 30 pts. All assignments must have BOTH the QUESTIONS and the ANSWERS. You can either E-mail me your SPELL CHECKED answers, or turn them in to your class's in-box in my room. Make sure that you have read over your answers SEVERAL times. Misspelled words will NOT be counted.

    Astronomical Distances

    For the next two questions, you'll need to continue along in the primer through the above website. Just the answer is not enough! You will also need to show your math in order to get credit!

    Astrophotography
  16. (1 pt.) If you wanted to take a picture through telescope you have to take a longer than normal exposure since the night is darker than the day. What are the two ways you can keep the telescope aligned with your target since the Earth's spin would make it blur?

    Meteor Impacts
  17. (1 pt) Why do scientists study moon dust to understand Earth's meteor impacts rather than on Earth?
  18. (1 pt.) How recently were the numbers of meteor impacts as great as when the Solar System was first forming?

    Water in Meteors
  19. (1 pt.) Why do scientists only seem to find evidence of evaporated water in meteorites, and not in its liquid form?

    Chondrites
  20. (1 pt.) Why are scientists so excited about finding carbonaceous chondrites?


    Bending Light
  21. (1 pt.) What is the law that explains the bending of light as it passes through a medium?

    EM Spectrum
  22. (1 pt.) Which part of the EM spectrum is the most energetic?

    Stars
  23. (1 pt.) When were scientists first able to observe x-ray emission from stars other than the sun?

    Sun
  24. (1 pt.) What seems to be the average length of the periodic cycle of sunspots?

    Supernovae
  25. (1 pt.) After a supernova explosion, of what is the left over core composed?

    Pulsars
  26. (1 pt.) How much would a teaspoonful of a neutron star weigh on Earth?
  27. (1 pt.) How and when were pulsars first detected?

    Dark Matter
  28. (1 pt.) How do scientists calculate the amount of matter in a given area of space?

    Origin & Destiny of the Universe
  29. (1pt.) What are the two possible ways the universe may come to an end?

    Map of Universe
  30. (1 pt.) What number is given to represent the greatest amount of red shift?

    Measuring Deuterium
  31. (1 pt.) According to the research team, when did the universe contain equal amounts of antimatter and matter?

    International Space Station's Current Location
  32. (1 pt.) Over what country is the International Space Station closest?

    Space Station Locator for Denver
  33. (1 pt.) When is the best day this week for you to observe the Space Station flying overhead? (hint: should be closest to when you wake up)

    Solar Pictures
  34. (1 pt.) What does a Solar Prominence look like?

    Solar Prominence Comparison
  35. (1 pt.) How much larger does a Solar Prominence appear than the size of the Earth?

    Trig Table
  36. (1 pt.) What is the cosine of 10 degrees divided by the cosine of 89 degrees?
    You must show the math to get credit!

    Trigonometry
  37. (1 pt.) Given x-y coordinates of a circle, which does the cosine of "t" (an angle) represent?

    Plasma Engines
  38. (1 pt.) How does the VASIMR engine generate thrust?
