What Are What are facts about Edwin Hubble?

Answer 1

Edwin Powell Hubble discovered that our galaxy was not the extent of the universe. Hubble was also the one to first realize that the universe is expanding. The Hubble Space Telescope was named in his honor.

Answer 2

Edwin Hubble was an American astronomer who played a crucial role in establishing the field of extragalactic astronomy. He is best known for his discovery of the relationship between redshifts and distances of galaxies, which led to the conclusion that the universe is expanding. Hubble also discovered that the universe is expanding at an accelerating rate, a phenomenon now attributed to dark energy. His work revolutionized our understanding of the cosmos and laid the foundation for the Big Bang theory.

Answer 3

He brought a wider understanding of galaxies, establishing that many other galaxies exist and that they appear to be moving, building on discoveries of other scientists. This was the basis for the theory of the expanding universe. He devised some of the ways that galaxies are now classified.

Answer 4

Hubble gave the idea that the universe is expanding, which has a lot of supporting data currently. The galaxies in the universe appear to be moving away from each other.

Answer 5

Edwin Hubble was the man who demonstrated that there were other galaxies other than the Milkey Way. This profoundly changed astronomy, and "increased" the size of the universe by many, many powers of ten. What is most interesting about Edwin Hubble? Well, let's do a short bio and touch on some things that might qualify. Edwin Hubble went to school and did well in all his studies, except spelling. He was early on recognized for his athletic abilities, and he set an Illinois state high jump record in 1906, where he made that jump and also took seven(!) firsts and a third - in one meet. He went on to earn a BS at the University of Chicago and went to Oxford as one of the first Rhodes Scholars. There he studied law, changed his major to Spanish, and earned his MA. Back in the United States he taught high school and coached Basketball at New Albany High School in New Albany, Indiana, which is right across the state line from Louisville, Kentucky. He passed the Kentucky bar, but never actually practiced law in Kentucky that is recorded. The Great War came. He rose through the ranks to major, and after the war he returned to astronomy at the University of Chicago's Yerkes Observatory. He completed his PhD in astronomy there in 1917. What among those things qualifies as "most interesting" as regards Dr. Hubble? As an astronomer, he worked with the instrument at Mount Wilson, the 100 inch Hooker Telescope, and in January of 1925 made the announcement that there were other galaxies in the universe. This stunning bit of news was denounced by a number of astronomers because it "couldn't be" that the universe was as large as implied by measurements of the distance to dust clouds Hubble imaged. This was a show stopper in the realm of astronomy, and in science in general. Here we are at the end of this little note, and we still haven't directly answered your question. But we've provided a link below to the Wikipedia post on this most remarkable man. You've got what you need right here, and you can choose what you want to work with.

Answer 6

He invented the Hubble telescope. Edwin Powell Hubble was born in the small town of Marshfield, Missouri, USA, on November 29th, 1889. In 1898, His family moved to Chicago, where he attended high school. Young Edwin Hubble had been fascinated by science and mysterious new worlds from an early age, having spent his childhood reading the works of Jules Verne.

Answer 7

He is known for:

1) Showing that other galaxies are not just nebula within the Milky Way galaxy, but galaxies separate and very far from the Milky Way galaxy.

2) Using red shift to show that all these other galaxies are moving away from our galaxy and that the further they are from us, the faster they are moving away. This is known as Hubble's Law. This led to our understanding of the expanding universe as well as supported the Big Bang theory.

3) The Hubble Sequence which is a classification of the types of galaxies.

Answer 8

Simple answer: Hubble proved that other galaxies exist beyond the Milky Way

Detailed answer: Edwin Hubble systematized the data showing the relation between distance and the redshift data, indicating increased redshift with increased distance.

Hubble did not believe that this indicated an expanding universe. Hubble believed the redshift was a "hitherto unrecognized principle of nature".

Here is a quote form Alan Sandage's review of Hubble 's work:

Hubble believed that his count data gave a more reasonable result concerning spatial curvature if the redshift correction was made assuming no recession. To the very end of his writings he maintained this position, favouring (or at the very least keeping open) the model where no true expansion exists, and therefore that the redshift "represents a hitherto unrecognized principle of nature". This viewpoint is emphasized (a)in The Realm of the Nebulae, (b) in his reply (Hubble 1937a) to the criticisms of the 1936 papers by Eddington and by McVittie, and (c) in his 1937 Rhodes Lectures published as The Observational Approach to Cosmology (Hubble 1937b). It also persists in his last published scientific paper which is an account of his Darwin Lecture (Hubble 1953).

Hubble was wise enough to know what he did not know. The redshift is still an "unrecognized principle" to most scientists.

The redshift is a manifestation of the centrifugal force indicating equilibrium of radial forces.

Answer 9

Edwin Hubble is important because of his excellent work in physics observation and analysis. Prior to Hubble, only Theoretical Work was honored.

Hubble still sets the standard analysis in that while his redshift work is the "evidence" for "Expanding Universe", Hubble felt the redshift was an "unrecognized principle of nature". Hubble is right, the redshift is an indicator of equilibrium, not expansion.

Answer 10

that the galaxies are moving away from each other
