stopped working. Forever
ESA announced that Herschel Space Telescope has ended April 29. There was no helium.
agency, of course, knew it would happen. Herschel Telescope instruments must be cooled to very low temperatures, close to absolute zero. ESA had used for this purpose liquid helium, but supplies of this element, which he took with him Herschel (approximately 2000 liters), were limited. A few weeks ago, the ESA announced that they have come to the end.
– I think we all agree that the Herschel mission was a huge success – says directing the research of Dr. Göran Pilbratt of the ESA.
telescope flown in space almost four years ago. His position observation is almost 1.5 million km from Earth. The device is equipped with a mirror diameter of 3.5 m, the largest piece I’ve ever flown in space. On board the Herschel instruments were also sensitive to different wavelengths of light, so that the telescope can observe the objects hidden behind clouds of dust.
OUT OF telescope will be directed by ESA in the Sun, whose orbit will remain forever, then communication with Earth will be terminated.
Herschel mission was to study the origins of stars and galaxies. Scan the sky in many wavelengths from the deep infrared to sub-millimeter waves. He was able to detect the coldest regions of space that was previously impossible. With it, the researchers found that in some parts of the universe with water.
Telescope has collected a lot of data, which now will have to be developed by the researchers.
