Hubble Space Telescope
Low Earth orbit

The Hubble Space Telescope (HST) is a telescope in orbit around the Earth, named after astronomer Edwin Hubble. Its position outside the Earth's atmosphere provides significant advantages over ground-based telescopes — images are not blurred by the atmosphere, there is no background from light scattered by the air, and the Hubble can observe ultraviolet light that is normally absorbed by the ozone layer in observations made from Earth. Though not the first space telescope, since its launch in 1990 it has become one of the most important instruments in the history of astronomy. With it, astronomers have made many observations leading to breakthroughs in astrophysics. Hubble's Ultra Deep Field has the most detailed visible light image of the most distant objects ever taken.
