Biography (1889 - 1953)
Edwin Powell Hubble
is renowned for determining that there are other galaxies in the
Universe beyond the Milky Way, and for observing that the
universe is expanding at a constant rate.
Hubble was a tall, elegant, athletic, man who at age 30 had an
undergraduate degree in astronomy and mathematics, a legal
degree as a Rhodes scholar, followed by a PhD in astronomy. He
was an attorney in Kentucky (joined its bar in 1913), and had
served in WWI, rising to the rank of major. He was bored with
law and decided to go back to his studies in astronomy.
In 1919 he began to
work at Mt. Wilson Observatory in California, where he would
work for the rest of his life. He was researching nebulae, fuzzy
patches of light in the sky. In 1924, he announced the discovery
of a Cepheid, or variable star, in the Andromeda Nebulae. Since
the work of Henrietta Leavitt had made it possible to calculate
the distance to Cepheids, he calculated that this Cepheid was
much further away than anyone had thought and that therefore the
nebulae was not a gaseous cloud inside our galaxy, like so many
nebulae, but in fact, a galaxy of stars just like the Milky Way.
Only much further away. Until now, people believed that the only
thing existing outside the Milky Way were the Magellanic Clouds.
The Universe was much bigger than had been previously presumed.
Hubble wanted to classify the galaxies according to their
content, distance, shape, and brightness patterns, and in his
observations he made another momentous discovery: By observing
redshifts in the light wavelengths emitted by the galaxies, he
saw that galaxies were moving away from each other at a rate
constant to the distance between them (Hubble's Law). The
further away they were, the faster they receded. This led to the
calculation of the point where the expansion began, and
confirmation of the big bang theory. Hubble calculated it to be
about 2 billion years ago, but more recent estimates have
revised that to 20 billion years ago.
An active anti-fascist, Hubble wanted to joined the armed forces
again during World War II, but was convinced he could contribute
more as a scientist on the home front. When the 200-inch
telescope was completed on Mt. Palomar, Hubble was given the
honour of first use. He died in 1953.
"Equipped with his five senses, man explores the universe around
him and calls the adventure Science."
