The European Space Telescope “Herschel” has surpassed the expectations of the astronomers: But now it is too hot for his instruments. In an orbit around the sun is Sendeschluss.div
The European Space Telescope “Herschel” comes after about three years of scientific work as planned out of service. “Herschel” has used up the necessary instruments for the supply of coolant. “The scientific part of the mission is now complete”, the Max Planck Institute for Solar System Research in Katlenburg-Lindau told in Göttingen on Tuesday.
The European Space Agency ESA had already announced on Monday, the telescope was calculated as previously overheated on his last journey. Further observations are not possible – so to speak Sendeschluss
“Herschel has exceeded all expectations and given us an incredible wealth of data with their evaluation astronomers will be busy for several years,” it said in the ESA. The space telescope has contributed as much to the knowledge of the formation of stars in distant galaxies.
new surprising findings
enthusiasm also at the Max Planck Institute Herschel had directed his unique view not only of distant galaxies and stars, “the Mission has also new and surprising insights about our solar system possible “. For example, a comet had been identified, the water ähnle the earth strong.
The 14 May 2009 transported into space telescope was equipped with a 3.5-meter primary mirror measured as particularly powerful. With cameras and scientific instruments more than 35,000 observations were recorded.
“Herschel” is more keep radio contact
“Herschel,” will remain on for some time with its radio contact with ground stations in order to implement a number of technical tests by the end of the cooling helium supply. In May, the telescope will then be transported to a long-term stable orbit around the sun.
The telescope was named after the German-born astronomer William Herschel (1738-1822), who discovered the planet Uranus, among other things, as well as infrared radiation and on the British King George III court . worked
One of the future space telescopes that can pursue “Herschel” observations, the “James Webb Space Telescope” (JWST), NASA, which is launched into space in 2018.
