The two keys to Edwin Hubble's breakthrough discovery were forged by others in the 1910s. The first key, the period-luminosity scale discovered by Henrietta Leavitt, allowed astronomers to ...

The Hubble constant is one of the most important numbers in cosmology because it tells us how fast the universe is expanding, which can be used to determine the age of the universe and its history. It ...

100 years ago, Hubble revealed a universe of galaxies that existed beyond ours — but he couldn't have done it without a little help. If we could go back 101 years, we would encounter a time when ...

But 100 years ago, astronomer Edwin P. Hubble (1889-1953), working at the Mount Wilson Observatory in California, made a stunning discovery: He calculated that a spiral nebula called Andromeda was ...
