That law states that the recessional velocity of a galaxy is equal to the galaxy's distance times 45 to 90 kilometers per second per megaparsec.
Variance in one law named for this man is caused by cosmic velocity dispersion. That law states that the recessional velocity of a galaxy is equal to the galaxy's distance times 45 to 90 kilometers per second per megaparsec. That value, whose reciprocal is the age of the universe, is this man's namesake constant. In 2013, an object honoring (*) NASA administrator James Webb will replace an item named for this man, which takes panoramic "deep field" images of distant galaxies. For 10 points, identify this astronomer, the namesake of an active space telescope.
