What was Edwin Hubble most important discovery?

Edwin Hubble, for whom the Hubble Space Telescope is named, was one of the leading astronomers of the twentieth century. His discovery in the 1920s that countless galaxies exist beyond our own Milky Way galaxy revolutionized our understanding of the universe and our place within it.

What star did Edwin Hubble discover?

Cepheid variable star
Hubble’s continued observations of Andromeda resulted in one of the most transformative discoveries in cosmology. He uncovered his first Cepheid variable star, a type of star used to measure distances in space by how it changes brightness.

How did Edwin Hubble benefit the world?

With his assistant at Mount Wilson, Milton Humason, Hubble measured the movement of galaxies. The two men did this by studying what Hubble called the “red shift.” It also is known as the “Doppler effect.” Hubble discovered that the farther away a galaxy is, the greater its speed.

What was Edwin Hubble’s theories?

Hubble’s Law basically states that the greater the distance of a galaxy from ours, the faster it recedes. It was proof that the Universe is expanding. It was also the first observational support for a new theory on the origin of the Universe proposed by Georges Lemaitre: the Big Bang.

What are Edwin Hubble’s main accomplishments?

What are three of Edwin Hubble’s facts?

Interest in the Universe and Science. He was very interested in the universe and science in general at a very young age.

What did Edwin Hubble do for a living?

Edwin Powell Hubble (November 20, 1889 – September 28, 1953) was an American astronomer. He played a crucial role in establishing the fields of extragalactic astronomy and observational cosmology and is regarded as one of the most important astronomers of all time.

What was Edwin Hubble’s nickname?

Often called a “pioneer of the distant stars,” astronomer Edwin Hubble (1889-1953) played a pivotal role in deciphering the vast and complex nature of the universe. His meticulous studies of spiral nebulae proved the existence of galaxies other than our own Milky Way.
