This man discovered a Cepheid variable in the Andromeda Nebula in the early 1920s and is also the namesake of a tuning-fork diagram used to classify galaxies.
One object named for this man was fixed in 1993 with the COSTAR instrument. That object named for this man will be succeeded by one named for James Webb in approximately five years. This man discovered a Cepheid variable in the Andromeda Nebula in the early 1920s and is also the namesake of a tuning-fork diagram used to classify galaxies. His namesake law, which includes a constant that is approximately seventy kilometers per second per megaparsec, gives the relationship between redshift and distance. That law named for this man shows that the universe is expanding. For 10 points, name this astronomer who also names a space telescope.
