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.
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.
1995 – Hubble Deep Field survey of galaxies in field 144 arc seconds across. 1998 – The 2dF Galaxy Redshift Survey maps the large-scale structure in a section of the Universe close to the Milky Way. 1998 – The Hubble Deep Field South is compiled. 1998 – Discovery of accelerating universe. [13]
It was here, 100 years ago, that Edwin Hubble noted a light in the distance that would lead to one of science's greatest discoveries. By night, astronomers kept watch at the best telescopes on Earth.
The Great Observatories Origins Deep Survey, or GOODS, is an astronomical survey combining deep observations from three of NASA's Great Observatories: the Hubble Space Telescope, the Spitzer Space Telescope, and the Chandra X-ray Observatory, along with data from other space-based telescopes, such as XMM Newton, and some of the world's most powerful ground-based telescopes.
The Hubble Space Telescope (HST or Hubble) is a space telescope that was launched into low Earth orbit in 1990 and remains in operation. It was not the first space telescope , but it is one of the largest and most versatile, renowned as a vital research tool and as a public relations boon for astronomy .
Hubble, assisted by Milton L. Humason, observed the magnitude of the redshift in many galaxies and published a paper in 1929 that showed the universe is expanding. The Hooker's reign of three decades as the largest telescope came to an end when the Caltech -Carnegie consortium completed its 200-inch (5.1 m) Hale Telescope at Palomar Observatory ...

Murrow High School, Brooklyn, New York; [58] Edwin Hubble Highway, the stretch of Interstate 44 passing through his birthplace of Marshfield, Missouri; [59] Hubble Middle School, a public school in Wheaton, Illinois, where he lived from 11 years old and up.
