  Hubble Space Telescope - Wikipedia, the free encyclopedia
Hubble's successor telescope, the James Webb Space Telescope (JWST), is due to be launched in 2013 and will be far superior to Hubble for most astronomical research programs.
Astronomers using the telescope to observe distant supernovae uncovered evidence that far from decelerating under the influence of gravity, the universe may in fact be accelerating.
Hubble images of the planet were sharper than any taken since the passage of Voyager 2 in 1979, and were crucial in studying the dynamics of the collision of a comet with Jupiter, an event believed to occur once every few centuries.

Il Telescopio Spaziale Hubble (abbreviato in HST dalle iniziali del nome inglese, o anche semplicemente Hubble) รจ un telescopio posto negli strati esterni dell'atmosfera terrestre, a circa 600 chilometri di altezza, in orbita attorno alla Terra (ogni orbita dura circa 100 minuti).
Hubble riprese eccezionali immagini della collisione della cometa Shoemaker-Levy 9 con il pianeta Giove nel 1994.
Nel dicembre 1995, Hubble riprese un'immagine chiamata lo Hubble Deep Field, una regione grande un trentesimo di milionesimo del cielo notturno e contenente numerose migliaia di deboli galassie.

The primary mirror of the Hubble telescope measures 2.4 m (8 ft) in diameter and weighs about 826 kg (1820 lbs).
Shortly after this image was taken, the Hubble telescope was shipped to Kennedy Space Center and loaded into the cargo bay of the shuttle Discovery.
The telescope measures 13.1 m (43.5 ft) in length, 4.27 m (14.0 ft) in diameter, and weighs 11,000 kg (25,500 lb).

 StarChild: The Hubble Space Telescope
The Hubble Space Telescope was named after Edwin Hubble, an astronomer whose contributions to astronomy include a classification system for galaxies and the Hubble Constant.
The Hubble Constant defines the relationship between a galaxy's distance from the Earth and the speed with which the galaxy is moving away from the Earth.
Hubble is controlled by scientists here on Earth who use gyroscopes to measure the rate at which Hubble is moving.

Data from the telescope is collected and analyzed by astronomers and scientists at the Space Telescope Institute, located at Johns Hopkins University in Baltimore, Maryland.
The telescope has been revisited several times by spacewalking astronauts in space shuttles in order to correct malfunctions, install new equipment, and boost the telescope back into a higher orbit (atmospheric drag causes Hubble to slowly fall out of orbit).
During the 1970's when Hubble was designed, the conventional wisdom was that ground based telescopes would never have the resolution of space telescopes because the atmosphere seeing limited the resolution of ground telescopes.

The Hubble Space Telescope - a joint ESA/NASA project - is a 2.4-meter reflecting telescope which was deployed in low-Earth orbit (600 kilometers) by the crew of the space shuttle Discovery (STS-31) on 25 April 1990.
HST is an observatory first dreamt of in the 1940s, designed and built in the 1970s and 80s, and operational only in the 1990s.
HST was designed with modular components so that on subsequent Shuttle missions it could be recovered and have faulty or obsolete parts replaced with new or improved instruments before being re-released into orbit.

Hubble also spotted a collection of possible brown dwarfs, which aren't large enough to sustain fusion reactions in their cores.
Astronomers have been able to use the Hubble Space Telescope's sensitive instruments to isolate the light from Sirius B and measure its mass by how its gravity bends light emitted from the star.
In addition to being incredibly powerful, Hubble is sensitive to ultraviolet light, which is reflected off of surface materials on the lunar surface.

 Wired News: Hubble Space Telescope: 1990-2007
The Earth-orbiting Hubble Space Telescope, once called the "best telescope in the universe" by astronomers and astronauts, will be taken off life support as early as 2007, NASA officials said.
Bill Readdy, head of space flight at NASA, defended the agency's decision to cancel the mission in a news conference on Monday, saying that it would be too difficult for NASA to prepare a second, backup shuttle on the ground in case of an emergency during the Hubble mission.
Hubble will be survived by the James Webb Space Telescope, an infrared observatory expected to be launched in 2011.

The new ground-based telescopes can do the job, and even the most ambitious of them, like the Keck in Hawaii and the Very Large Telescope (VLT) in Chile, are much less expensive than the Hubble and much more sensitive to light.
For example, the VLT cost was roughly 1/7 of the HST cost, and gave the astronomic community four 8.2 meters telescopes, with a resolution almost as high as the Hubble.
