Europe will launch spacecraft to explore the mystery of the Big Bang (Map)
British "Observer" reported on the 4th, scientists have unveiled the world's lowest temperature of the spacecraft on the veil: a weight of 2 tons of spacecraft, the spacecraft's instruments will be as low as one tenth of the absolute zero (about -273.15 ° C) frozen, this may be the lowest temperature of the natural world.
Planck spacecraft built by the European Space Agency, which will remain in the Earth one million miles away in space, look for the Big Bang 14 billion years ago, when the remaining traces of radiation. Ship with Truck Size of the spacecraft will use frozen to -273 degrees search tool traces of the Big Bang, to avoid any signs of heat damage results. Purpose is to find the initial formation and later gathered into stars, galaxies and how important living things in the end.
Spacecraft also search for "dark energy" and "dark matter", said the two mysterious entities, permeate the universe, but scientists have still not found. Dark energy can be explained with the previous theory that the comparison, why the expansion of the universe much faster. No. Planck mission scientist Jane? Tubal said: "The components of the universe after the big bang the universe created the first time, this task will allow us to return to that period, to identify why the universe is like this. "
Scientists believe, almost a cosmic explosion, the structure appeared in subtle changes. These changes subsequently formed from atoms, stars and galaxies has been verified. To study these changes, ship to the German physicist Max? Planck spacecraft will be named the Big Bang through the analysis of microwave radiation left by small changes, draw a map of the upper atmosphere. Cambridge University Professor George said: "The differences in the temperature of the natural state. This is a very delicate task." The key is to let the Planck number remain in space an incredible low.
Imperial College London astrophysicist Andrew? Said Dr. Jeff: "No. Max Planck radiation will change in the measure of each fine. This means that we can not use a false signal from the detection tool Therefore, we must try to maximize the numbers on the Planck absolute zero temperature is kept around. "no less than the absolute zero-273.15C of the. However, scientists in the laboratory can be cooled to near the temperature of the object. To do so in space is a different story, it stumped Project Masters. Result, they developed a device that require ultra-high power electric three Refrigerator To create an extremely low temperature of the spacecraft. No.
Planck space exploration program is undertaken by the European Space Agency, one of the most difficult task, Planck number is scheduled to July 31 next year, also a major European Detector No. Herschel (Herschel) with Launch Off. Once the world's largest space Telescope Into space Herschel spacecraft will collect information from stars IR Radiation, aimed at identifying the details of star formation. The total cost of these two tasks as much as 1 billion pounds. However, up to now has not completed a stand-detectors, Herschel Planck number and number will be used in conjunction with Ariane 5 launch vehicle into space, Ariane 5 rocket launches in recent there have been several major mistakes. The plan, a scientist, admits: "For us, the next year in July will be a very difficult time."
