The Hubble Space Telescope (HST) is a
telescope in
orbit around the Earth, named after astronomer
Edwin Hubble for his discovery of galaxies outside the
Milky Way and his creation of
Hubble's law, which calculates the rate at which the universe is expanding. Its position outside the
Earth's atmosphere allows it to take sharp optical images of very faint objects, and since its launch in 1990, it has become one of the most important instruments in the history of
astronomy. It has been responsible for many ground-breaking observations and has helped
astronomers achieve a better understanding of many fundamental problems in
astrophysics. Hubble's
Ultra-Deep Field is the deepest (most sensitive) astronomical optical image ever taken.
