In the year 2009, NASA has launched its Kepler Space Telescope whose main aim was to discover some few hundred exoplanets. Exoplanets are the stars which are said to be orbiting outside of the solar system. Till now Kepler has discovered 2,600 planets outside the solar system.
NASA has now retired Kepler space telescope as it has run out of fuels after a decade-long mission in which it detected about thousands of planets that are existed beyond our solar systems. On Tuesday, NASA was able to boost its search for the worldwide planet to know whether these planets can harbour alien life.
It was originally designed to look for the Earth which is like planets in the habitable zone of the stars which is like the sun. But in place of that Kepler was seen to found a rich diversity of planets which is around many types of stars.
This new telescope has laid with the bare of the diversity of planets which have to reside in our Milky Way galaxy. These type of findings indicates the distant star systems which are populated with billions of planets as well as they helped in pinpointing the first moon that was present outside of the solar system.
The positioning system has broken down in the year 2013 which is said to be about four years after the launch. But after that scientists have found their way to keep it in operational mode but now as telescope has run out of fuel, the telescope has now retired from the mission.
Kepler has got successor which is the new Transiting Exoplanet Survey Satellite (TESS). The satellite was launched in April. Currently, the European Space Agency is said to testing the Characterising Exoplanet Satellite (Cheops) which is said to be capable of measuring the density of the planets around the other stars.
