Edwin Powell Hubble (November 20, 1889 – September 28, 1953) [1] was an American astronomer. He played a crucial role in establishing the fields of extragalactic astronomy and observational cosmology .
Comet Hubble, formally designated C/1937 P1, is the first and only comet discovered by astronomer Edwin Hubble. The comet was already on its outbound flight when it was first spotted in August 1937 as a magnitude 13.5 object in the constellation Sagittarius. [1] [5] It is the fourth comet discovered in 1937.

In 1929, American astronomer Edwin Hubble's discovery of the expanding universe implied that between 10 billion and 20 billion years ago, the entire universe was contained in one singular extremely dense place. This discovery brought the concept of the beginning of the universe within the province of science.
Hubble's idea allowed for two opposing hypotheses to be suggested. One was Lemaître's Big Bang, advocated and developed by George Gamow. The other model was Fred Hoyle's steady-state model, in which new matter would be created as the galaxies moved away from each other. In this model, the universe is roughly the same at any point in time.
The non-standard object SCP 06F6 was discovered by the Hubble Space Telescope in February 2006. [175] [176] On March 3, 2016, researchers using Hubble data announced the discovery of the farthest confirmed galaxy to date: GN-z11, which Hubble observed as it existed roughly 400 million years after the Big Bang. [177]
Spiral galaxy UGC 12591 is classified as an S0/Sa galaxy. [1]The Hubble sequence is a morphological classification scheme for galaxies invented by Edwin Hubble in 1926. [2] [3] It is often known colloquially as the “Hubble tuning-fork” because of the shape in which it is traditionally represented.
This was one of the most important discoveries in physical cosmology since Edwin Hubble demonstrated in the 1920s that the universe was expanding. It provided the evidence that confirmed George Gamow's and Georges Lemaître's "Big Bang" theory of the creation of the universe. This helped change the science of cosmology, the study of the ...
Edwin Hubble discovered that the universe is expanding and that the farther away a galaxy is, the faster it is moving away from us. Two years later, Georges Lemaître suggests that the expansion can be traced to an initial "Big Bang".
