Introduction. telescope time is a valuable commodity in astronomy, so astronomers plan their observations carefully. one of the first steps is to choose what type of observation to make. recall that three basic types of astronomical observation are imaging (taking a photograph of an object), spectroscopy (spreading an object's light into a spectrum), and timing (measuring how an object's light varies with time).
part a: sort each of the astronomical questions below into the appropriate bin based on the type of observation you would need to perform to answer it.
three categories: imagine, spectroscopy and timing
the questions:
1. "what are the major surface features of mars? "
2. "what is the temperature of jupiter's atmosphere? "
3. "does the star mira vary in brightness? "
4. "how large is the andromeda galaxy? "
5. "what is the chemical composition of the crab nebula? "
6. "is the x-ray emission fro the galactic center steady or changing? "
7. "is the star vega moving toward us or away from us? "
8. "are stars in the orion nebula surrounded by dusty disks of gas?
