The Invisible Sky: ROSAT and the Age of X-Ray Astronomy

ROSAT, the ROentgen SATellite launched in 1990, has revealed an entirely new aspect of the night sky - that of objects emitting X-rays rather than the rays of light visible to the human eye. This lavishly illustrated book is the first to describe one of the most remarkable instruments in modern astronomy. It offers fascinating images and engaging accounts of a wide range of Solar-System and deep space objects such as Comet Hyakutake, the Sun, the Moon, and objects outside the Milky Way.

Bernd Aschenbach was a founding member of the ROSAT design team. His distinguished career includes many awards, the most recent being the Carl Zeiss Research Prize.

Hermann-Michael Hahn is freelance science writer who regularly appears on TV, on radio, and in newspapers. He has written several books on astronomy and is an accomplished translator.

Jochaim Trmper is the director of the Max Planck Institute for Astrophysics and was the director of ROSAT design and construction. He currently directs the team that collects and interprets ROSAT data. He is the recipient of numerous scientific awards, including the Karl Schwarzschild Medal of the German Astronomical Society.
