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 .

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.
In 1924, Edwin Hubble announced the distance to M33 Triangulum. [citation needed] Andromeda Galaxy: 1923–1924: In 1923, Edwin Hubble measured the distance to Andromeda, and settled the question of whether or not there were galaxies, or if everything was in the Milky Way. Small Magellanic Cloud: 1913–1923: This was the first intergalactic ...
The same galaxy would look very different, if viewed edge-on, as opposed to a face-on or 'broadside' viewpoint. As such, the early-type sequence is poorly represented: The ES galaxies are missing from the Hubble sequence, and the E5–E7 galaxies are actually S0 galaxies. Furthermore, the barred ES and barred S0 galaxies are also absent.
The observational result of Hubble's law, the proportional relationship between distance and the speed with which a galaxy is moving away from us, usually referred to as redshift, is a product of the cosmic distance ladder. Edwin Hubble observed that fainter galaxies are more redshifted. Finding the value of the Hubble constant was the result ...

The film transports the audience through a series of environments, such as Mount Wilson Observatory in the early 1920s, when Edwin Hubble discovered the true nature of the Andromeda Galaxy and the expansion of the Universe. Over the desk of an anonymous modern researcher, we see a representation of the Big Bang. The device of transforming raw ...
