In Depth: Hubble Space Telescope
The Hubble Space Telescope's launch and deployment in April 1990 marked the most significant advancement in astronomy since Galileo's telescope. The first major optical telescope to be placed in space, Hubble operates from the ultimate mountaintop. Far above the distortion of Earth's atmosphere, clouds and light pollution, Hubble has an unobstructed view of the universe.
Hubble can see far more than what we can with our eyes. Its domain extends from the ultraviolet, through the visible, and to the near-infrared.
The telescope has had a major impact on every area of astronomy, from the solar system to objects at the edge of the universe. Scientists have used Hubble to observe the most distant stars and galaxies as well as the planets in our solar system.
Data and from the orbiting telescope are the backbone of more than 15,000 technical papers. It also, of course, continues to dazzle us with stunning pictures of stars, galaxies and planets.
Hubble gave us one of the most memorable and important images in human history: the Hubble Deep Field image which shows thousands of galaxies in just a tiny speck of sky.
Hubble has operated far beyond its planned lifetime, but it has needed some repair work.
Shortly after Hubble Space Telescope was deployed in 1990, the observatory's primary mirror was discovered to have an aberration that affected the clarity of the telescope's early images.
Fortunately, Hubble was the first telescope designed to be visited in space by astronauts to perform repairs, replace parts, and update its technology with new instruments. Astronauts repaired Hubble in December 1993.
Including that trip, there were five astronaut servicing missions to Hubble.
Since its fifth and final repair mission in 2009, the telescope has made over 1.4 million observations, located distant swirling galaxies and plotted pockets of dark matter.
Analysis of Hubble’s images even helped earned scientists the Nobel Prize in 2011 for discovering that the rate that our universe is rapidly accelerating.
In short, when Earth has questions, Hubble answers.
