"Kepler" flew over space on nine and provided, among other things, evidence of thousands of exoplanets. As expected, the space telescope has no more fuel – but the successor is already on the way.
After about nine years in space, the space telescope "Kepler" has run out as planned. The telescope has been removed, said Tuesday the local US agency Nasa (local time) during a brief press conference. "Kepler" should remain in a safe orbit around the sun. "The time has come," wrote Thomas Zurbuchen, head of NASA, on the Twitter messaging service. "Thank you for changing our vision of the universe."
The time has come. As expected, @NASAKepler is running out of fuel. 500,000 stars and galaxies have discovered more than 2,600 planets beyond our solar system, thanks for changing our vision of the universe! https://t.co/tNnzdPlMkG

Named after the German astronomer Johannes Kepler (1571-1630), the planet hunter was orbited in 2009 to search for planets outside our solar system. Since then, Kepler has found evidence of thousands of distant planets.
"Kepler" opened the exoplanetology
"When we started thinking about this mission 35 years ago, we did not know any planet outside our solar system," said former NASA researcher William Borucki. "We now know that planets are everywhere." However, the mission also encountered technical difficulties. Since 2013, "Kepler" only works in limited mode.
"As NASA's first planetary hunter, Kepler far exceeded our expectations and paved the way for our discoveries and the search for life in our solar system and beyond," said the director. NASA, Zurbuchen. "Kepler's not only showed us the number of possible planets, but opened up a whole new field of research that has taken the scientific community by storm." More recently, researchers had been able to download a large amount of data from Kepler. ,
"Tess" covers more than "Kepler"
A successor to "Kepler" has already announced: In April, the US State of Florida's "Transiting Exoplanet Survey Satellite" (TESS) space telescope launched a planet search in space. The $ 200 million mission is initially planned for about two years. Tess is about the size of a refrigerator and has four cameras.
Like "Kepler", the telescope observes the light of certain stars. If this dissipates, it could mean that a planet has pbaded. "Tess" could find both small stony planets and huge celestial bodies – and should cover a much larger area than "Kepler".
