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 .
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 ...
Orbiting Hubble Space Telescope; Edwin P. Hubble Planetarium, located in the Edward R. 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.

A mandala creates a world center within the boundaries of its two-dimensional space analogous to that created in three-dimensional space by a shrine. [6] In medieval times some Christians thought of Jerusalem as the center of the world (Latin: umbilicus mundi, Greek: Omphalos), and was so represented in the so-called T and O maps. Byzantine ...
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.
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.
1922 – Alexander Friedmann finds a solution to the Einstein field equations which suggests a general expansion of space. 1923 – Edwin Hubble measures distances to a few nearby spiral nebulae (galaxies), the Andromeda Galaxy (M31), Triangulum Galaxy (M33), and NGC 6822. The distances place them far outside the Milky Way, and implies that ...
Shapley's research marked the transition from heliocentrism to galactocentrism, [5] [6] [7] placing the Galactic Center of the Milky Way Galaxy far away from the Sun, towards Sagittarius. Heber Doust Curtis and Edwin Hubble further refuted the heliocentric view of the universe by showing that spirals are themselves far-flung galactic systems ...
