What is Hubble?

Hubble is an 11-ton telescope in orbit 600 kilometers from the earth. The name Hubble comes from the famous astronomer Edwin Hubble. It was this telescope that allowed to have spectacular images of the collision of the comet Shoemaker-Levy 9 with the planet Jupiter. The Hubble telescope was launched by Space Shuttle Discovery on April 24, 1990. Since then, the images taken by this telescope have steadily improved thanks to the new digital technologies and the repeated visit of astronauts Which modified some defects regarding its operation. Currently, NASA reflected on a launch of a new generation telescope, knowing that Hubble has already 20 years of existence. Moreover, on this occasion, the search engine Google celebrates this 20th anniversary by replacing its usual logo with that of the telescope Hubble.
