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.

"e;Relativistic Astrophysics and Cosmology"e; have developed into important and fruitful research areas with a hitherto unprecented public interest. The year 2005, which marked the 100th anniversary of the 'annus mirabilis', that year in which Albert Einstein published three of his most important scientific papers, was the perfect opportunity to review and to present the current scientific understanding of relativistic topics including cosmological models, cosmology related measurements, the large scale properties of the Universe, dark matter and dark energy, the theory of gravity, black holes, theory and measurements, active galactic nuclei, clusters of galaxies, jets. Each of these subjects is addressed and the book represents a useful reference tool both for the expert and the new-comer in these fields.
