Extreme Ultraviolet Satellites Open New View of the Sky

摘要

Each time astronomers open a new window on the cosmos, a stream of surprises pours in. Radio telescopes found pulsars and noisy "radio galaxies"; infrared detectors probed clouds of cool dust and gas where stars are born; orbiting gamma ray telescopes detected gamma ray bursts. Now astronomers have yet another window in the electro-magnetic spectrum: satel-lites that can detect and analyze extreme ultraviolet (EUV) radiation.
