Nasa has launched its latest orbiting X-ray observatory. The Nuclear Spectroscopic Telescope Array (Nustar) was sent into space on a Pegasus rocket operated out of the Kwajalein Atol in the central Pacific.Nustar will study high-energy X-rays coming from exotic sources such as black holes, exploded stars and the hot gas in galaxy clusters. The observatory …
