Telescopes are one of the greatest inventions of the human being which have helped scientists lay down a map of the universe.
The invention of telescopes has helped in discovering new elements from various celestial bodies. Telescopes have helped scientists keep a track over the movements of various stars and plants and they also assist in keeping a lookout for any asteroids that may be in the course of earth’s orbital axis. Here is a list of the most powerful telescopes that are currently being used in and around the globe,
1) Hubble Space Telescope –
The Hubble space telescope was launched in the year 1990 by NASA and The European space agency. This telescope is famous for capturing images of the deep field, the Crab Nebula and the Eagle Nebula. A recent trip by the space shuttle mission to the Hubble has upgraded the telescope with new gear that’ll keep it running and viable till 2020.
2) Keck Observatory –
The Keck Observatory is located in Mauna Kea, Hawaii. It is owned and operated by Caltech and the University of California. The Keck Observatory is located on a separate island and a two identically shaped building each about 33 ft in diameter. They were built in the, and their advanced adaptive optics paved the way for computer operated mirrors which can be adjusted multiple times per second to make up for the atmospheric disturbances in real time.
3) Fermi Gamma-Ray Space Telescope –
The Fermi Gamma-Ray Space Telescope was launched in the year 2008 and is owned and operated by NASA, the U.S Department of Energy, Germany, France, Japan, Italy, and Sweden. It revolves around the lower orbit of the earth. It is used to measure the most powerful radiation in the universe such as Supermassive black holes, collisions of neutron stars and bursts of gamma rays that carry way more energy than anything on earth.
4) Large Binocular Telescope –
The Large Binocular Telescope was built in the year 2002 and is a collaboration between US, Germany, and Japan. It is located on Mount Graham, in the Pinaleno Mountains of southeastern Arizona, USA. The Large Binocular Telescope is one among the world’s most advanced optical telescopes as it uses two 8.4 m wide mirror with its center 14.4 m apart.
5) Spitzer Space Telescope –
The Spitzer Space Telescope was launched in the year 2003 and is owned by NASA, Caltech, and JPL. Spitzer is an infrared telescope. It is the last of NASA’s four greatest observatories. NASA had estimated that by April 2007 the telescope would exhaust its onboard helium supply, but the helium supply lasted till October, and the Spitzer team were able to compile the stunning images of multiple generations of star formation.
