Inhaltsangabe
The x-ray satellite ROSAT, launched in 1990, has made a new universe visible. It has discovered over 120, 000 x-ray sources and allowed us for the first time to look in new ways at stellar explosions, galactic collisions, extremely compact pulsars, black holes, and quasars that shine 10, 000 times more strongly than the brightest galaxy. It has detected x-rays from Comet Hyakutake and from the Moon. ROSAT is one of the most successful scientific instruments ever launched. In The Invisible Sky, two of the scientists who were instrumental in the design and launching of the satellite team up with a well-known science journalist to chronicle the beginnings, early failures, planning and construction, and deployment of this most famous of x-ray observatories. They describe the cutting-edge science being done with it and show many of the most spectacular color images it has generated. This beautifully illustrated book is the first to describe for lay readers one of the most rmearkable instruments in modern astronomy.
Von der hinteren Coverseite
Since ROSAT, the ROentgen SATellite (named after Wilhelm Roentgen, a German physicist credited with discovering x-rays), launched in June of 1990, it 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.
