The Invisible Sky tells the story of one of the most successful scientific instruments ever launched through the words of two of the scientists who were instrumental in the design and launching of the satellite, along with Hermann-Michael Hahn, an accomplished science journalist. This extraordianry collaboration chronicles the beginnings, early failures, construction, and deployment of the most famous of X-ray observatories in a highly readable account of cutting-edge science illustrated with spectacular colour images from ROSAT.

„Relativistic Astrophysics and Cosmology“ 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.
