BORN IN MARSHFIELD ,MISSOURI ON NOVEMBER 20 1889

He found a constant relationship between galaxies' redshift and distance, which helped to eventually prove that the universe is expanding

Redshift -

At least three types of redshift occur in the universe — from the universe's expansion, from the movement of galaxies relative to each other and from "gravitational redshift," which happens when light is shifted due to the massive amount of matter inside of a galaxy

happens when light or other electromagnetic radiation from an object is increased in the wavelength

WON A NOBEL PRIZE FOR HIS WORK IN THE FIELD OF PHYSICS

HE HAS HIS OWN CLASSIFICATION SYSTEM KNOWN AS THE HUBBLE SEQUENCE

While working in Mount Wilson he proved that other galaxies existed outside the milky way

The expanding-universe theory has largely been accepted by scientists worldwide. Hubble's and Humason's research work also helped prove that galaxies must come from a central point of origin, and was used by some scientists to support the Big Bang Theory—one of the most popular theories on the universe's origin, which was first suggested by Georges Lemaître in 1927.

Edward Hubble still remains one of the word's most famous astronomers

he died on September 28, 1953. He had suffered a stroke that was caused by cerebral thrombosis, and was 63 years old at the time.

As a tribute to Hubble's groundbreaking work in astrophysics, NASA named its Hubble Space Telescope after Edwin Hubble
