XEUS is the X-ray Evolving Universe Spectroscopy space observatory that is being developed by the European Space Agency as a successor to the successful XMM-Newton X-ray satellite telescope. It consists of a mirror spacecraft that carries a large X-ray telescope, with a mirror area of about 5 m² and an imaging resolution better than 5″ for X-ray radiation with an energy of 1 keV. A detector spacecraft will fly in formation with the telescope at a distance of approximately 35 m, in the focus of the telescope. The detectors will include a wide-field X-ray imager with an energy resolution of 150 eV at 6 keV, as well as a cryogenic narrow-field imager with an energy resolution of 2 eV at 1 keV.
