1) The Hubble Space Telescope (HST) is a telescope in orbit around the Earth, named after astronomer Edwin Hubble

2) Its position outside the Earth's atmosphere provides significant advantages over ground-based telescopes such as
a) Images are not blurred by the atmosphere
b) There is no background from light scattered by the air
c) It can observe ultra-violet light that is normally absorbed by the
ozone layer in observations made from Earth

3) The Hubble is the only telescope ever designed to be serviced from space by astronauts

4) Hubble has helped to resolve some long-standing problems in astronomy such as
a) Measure distances to Cepheid variable stars more accurately than ever before
b) constrain the value of the Hubble constant, the measure of the rate at which the universe is expanding, which is also related to its age
c) Other major discoveries are proto-planetary disks (proplyds) in the Orion Nebula;evidence fo ...more

The Hubble Space Telescope is one of the most important telescopes in the history of astronomy. Since its launch in 1990 it has been responsible for many ground-breaking observations and has helped astronomers achieve a better understanding of many fundamental problems in astrophysics.

Named after the trailblazing astronomer Edwin P. Hubble (1889-1953).Since its launch in 1990 it has been responsible for many ground-breaking observations and has helped astronomers achieve a better understanding of many fundamental problems in astrophysics. NASA's Hubble and Spitzer Space Telescopes have joined forces to discover nine of the smallest, faintest, most compact galaxies ever observed in the distant universe. Blazing with the brilliance of millions of stars, each of the newly discovered galaxies is a hundred to a thousand times smaller than our Milky Way Galaxy.

"These are among the lowest mass galaxies ever directly observed in the early universe," says Nor Pirzkal of the Space Telescope Science Institute and the European Space Agency in Baltimore, Md.
