It was repaired in 1993 due to problems in the picture quality.

It found there were actually many galaxies even there, but very faint and very far away. No other telescope could have seen that.<ref>{{cite web\|title=Hubble Breakthroughs\|url=http://hubblesite.org/hubble_discoveries/breakthroughs/\|publisher=HubbleSite\|accessdate=31 March 2013}}</ref> * In 2004, Hubble looked back several billion years to the first galaxies in the [[Hubble Ultra Deep Field]]. * It was able to help settle the [[age of the universe]] at about 13.7 billion years. Before the Hubble, scientists only knew it was between 10 and 20 billion years old. * It took the first picture of a [[extrasolar planet\|planet outside]] our [[Solar System\|solar system]], and was able to find what type of atmosphere other planets might have. == ~~Future~~Replacement == Hubble ~~will~~has bebeen replaced by the [[James Webb Space Telescope]] which ~~will be~~is located even further from Earth. There are now other telescopes in orbit, like the [[Herschel Space Observatory]], the [[Spitzer Space Telescope]] and the [[Kepler (spacecraft)\|Kepler Spacecraft]], which was specially made for finding Earth-like planets around other stars.<ref>{{cite web\|title=Telescopes in Space\|date=18 May 2009 \|url=http://www.space.com/6717-bounty-space-telescopes-fuels-golden-age-astronomy.html\|publisher=Space.com\|accessdate=31 March 2013}}</ref> == Other Websites==▼ [http://www.nasa.gov/mission_pages/hubble/main/index.html NASA Hubble Site]▼ [http://hubblesite.org/ HubbleSite (STSI)]▼ == References == {{reflist}} ▲== Other ~~Websites~~websites == ▲[http://www.nasa.gov/mission_pages/hubble/main/index.html NASA Hubble Site] ▲[http://hubblesite.org/ HubbleSite (STSI)] {{authority control}} [[Category:Space telescopes]] [[Category:Spacecraft launched in the 1990s]]
