A quasar has a brightness that corresponds to apparent magnitude 14.6 (Unit 55.4). a. If it is 1.29 billion pc away, how many times brighter than the Sun is it? The quasar is × 1011 times brighter than the Sun. b. How does this compare to the brightness of the Milky Way? Assume that the Milky Way contains about 1011 stars. The quasar is times brighter than the Milky Way.

Quasars are faint, distant sources of radio waves. (Quasar is short for "quasi-stellar source." They are so named because, like a star, they appear to the astronomer to be pointlike.) From the shift in the frequency of their emitted light toward the red, called the "redshift," we know that quasars are moving very fast. Astronomers observe that the more distant an object is from the earth, the faster it moves. In this way they determine that quasars are billions of...
