______ 2. device that separates light into wavelengths
______ 3. the study of the universe
______ 4. the group of stars containing the sun
______ 5. the outer surface of the sun
______ 6. patterns of stars that look like pictures

______ 11. type of star that results when hydrogen fuel is used up
______ 12. line on the h-r diagram that includes the sun
______ 13. the name of the cluster of galaxies to which the milky way belongs
column ii
a. spectroscope
b. giant
c. constellations
d. dark matter
e. photosphere
f. sunspots
g. milky way galaxy
h. local group
i. white dwarf
j. light–year
k. galaxy
l. cosmology
m. main sequence

Explanation:

1. The distance light travels in one year is defined as a light - year, so match 1 with j.
2. A spectroscope is a device that separates light into wavelengths, so match 2 with a.
3. Cosmology is the study of the universe, so match 3 with l.
4. The Milky Way Galaxy is the group of stars containing the Sun, so match 4 with g.
5. The photosphere is the outer surface of the Sun, so match 5 with e.
6. Constellations are patterns of stars that look like pictures, so match 6 with c.
7. A galaxy is a collection of billions of stars, so match 7 with k.
8. A white dwarf is a kind of star that forms from a giant star, so match 8 with i.
9. Dark matter explains the rotation of the Milky Way, so match 9 with d.
10. Sunspots are areas of the Sun that are cooler than surrounding regions, so match 10 with f.
11. A giant star is a type of star that results when hydrogen fuel is used up (wait, correction: When hydrogen fuel is used up, a star can become a giant, and then later evolve. But according to the options, the type of star that results when hydrogen fuel is used up is a giant? Wait, no, the main sequence star uses up hydrogen and becomes a giant. Wait, the option for 11: the question is "Type of star that results when hydrogen fuel is used up" and option b is giant. So match 11 with b.
12. The main sequence is the line on the H - R diagram that includes the Sun, so match 12 with m.
13. The Local Group is the name of the cluster of galaxies to which the Milky Way belongs, so match 13 with h.

Answer:

1. j
2. a
3. l
4. g
5. e
6. c
7. k
8. i
9. d
10. f
11. b
12. m
13. h
