21st CENTURY ASTRONOMY
Edwin Hubble was born in Missouri in 1889. Hubble’s experience allowed him to lead a research team in the field of astrophysics at Mount Wilson Observatory in California. One of his accomplishments was discovering an expanding universe with Milton by using the Doppler shift and single headedly disproved the theories of relativity and special relativity at the same time. He was a dedicated scientist and also created a classification system for galaxies known as the Hubble sequence. In 1920 Harlo Shapley thought the Milky Way Galaxy contained every star in the universe while Huber D. Curtis claimed it was one of many galaxies.

Hubble finally proved Curtis to be right. In Oct. of 1923 Hubble discovered the Andromeda galaxy which proved that the Milky Way Galaxy was not the only galaxy in the Universe. Hubble was a successful lawyer, was a world war ll veteran, and had a Doctorate in astronomy.  He went on to win a Nobel Prize in physics by proving other galaxies existed beyond the Milky Way galaxy by comparing degrees of luminosity among variable  stars. Hubble died in 1953; he was 63. He and his wife, Grace, had no children.

The Hubble Telescope Launched in 1990 now has a new helper the IBEX telescope, The NASA Kepler orbiting observatory (launched 2009) and Spitzer telescopes designed to find distant planets revolving around a s tar and objects in the cosmos. The largest telescope is the Keck located in Hawaii. The James Webb Telescope with its 111 sq. meter mirror is to be launched in 2020. It has a large binocular telescope, is 10 xs’s sharper and can see 12 billion light years away. The “LIGO” instrument, located at the Hanford Nuclear Reservation in Washington is an improved gravity wave detector and is replacing the “GWD”  gravity wave detector. As of 2015, no gravity waves have been detected.
