By the end of 2007 the final stage of the assembly is scheduled Observatory far-infrared Herschel (European Space Agency, ESA). The purpose of this observatory - the study of the formation and evolution of stars and galaxies.
Satellite Herschel, designed specifically to study the formation of galaxies and stars, to be launched in mid-2008, together with the satellite Planck, which will make a map of microwave activity in space to study the early stages of the formation of the universe.
Herschel is equipped with the largest telescope ever launched into space (its diameter - 3.5 meters). It will give scientists more opportunities to study the universe in the far-infrared and sub-millimeter-wave radiation. Studying the light on this wavelength, scientists can see the so-called "Cold" universe. Herschel will provide unprecedented still image, helping scientists to look into the distant regions of star formation, the centers of galaxies and planetary systems.
To successfully perform their tasks in the detection of weak radiation coming from the coolest objects of space, Herschel detectors must operate at very low temperatures. The spacecraft is equipped so as to cool the detectors to just above absolute zero (-273.15
