Hubble From the Power Comes the Change 1080p HD


The Hubble Space Telescope (HST)

From Wikipedia:

Is a space telescope that was carried into orbit by the space shuttle in 1990. Although not the first space telescope, Hubble is one of the largest and most versatile, and is well-known as both a vital research tool and a public relations boon for astronomy.

The HST was built by the United States space agency NASA, with contributions from the European Space Agency, and is operated by the Space Telescope Science Institute. It is named after the astronomer Edwin Hubble.

The HST is one of NASA’s Great Observatories, along with the Compton Gamma Ray Observatory, the Chandra X-ray Observatory, and the Spitzer Space Telescope.Space telescopes were proposed as early as 1923.

Hubble was funded in the 1970s, with a proposed launch in 1983, but the project was beset by technical delays, budget problems, and the Challenger disaster. When finally launched in 1990, scientists found that the main mirror had been ground incorrectly, severely compromising the telescope’s capabilities.

However, after a servicing mission in 1993, the telescope was restored to its intended quality. Hubble’s orbit outside the distortion of Earth’s atmosphere allows it to take extremely sharp images with almost no background light. Hubble’s Ultra Deep Field image, for instance, is the most detailed visible-light image ever made of the universe’s most distant objects.

Many Hubble observations have led to breakthroughs in astrophysics, such as accurately determining the rate of expansion of the universe.Hubble is the only telescope ever designed to be serviced in space by astronauts. Four servicing missions were performed from 1993 to 2002, but the fifth was canceled on safety grounds following the Space Shuttle Columbia disaster.

However, after spirited public discussion, NASA administrator Mike Griffin approved one final servicing mission, completed in 2009. The telescope is now expected to function until at least 2014, when its ‘successor’, the James Webb Space Telescope (JWST), is due to be launched.

Hubble Story

A journey of Hubble through space and time.

The NASA/ESA Hubble Space Telescope is one of the biggest scientific projects of all time.  To mark the 15th anniversary on 24 April 2005, the European Space Agency presented a series of unique activities in collaboration with partners all over Europe.

Dancing with the stars

From the editor Violine:

Data & Animations Nasa Hubble Space Telescope. The galaxies, containing a vast number of stars, swing past each other in a graceful performance choreographed by gravity.  I wanted to combine this wonderful song to these splendid animations that I had in files for a while.  I hope you will enjoy it !
