This book deals with the evolution of X-ray astronomy during the initial phases of its development. Three transformations of astronomy as a discipline are highlighted: the augmentation of purely optical observations; the emergence of federal funding as the dominant source of financial support; and the greatly altered size and structure of the research community.

From the discovery of entirely new kinds of galaxies to a window into cosmic ‘prehistory’, Bothwell shows us the Universe as we’ve never seen it before – literally. Since the dawn of our species, people all over the world have gazed in awe at the night sky. But for all the beauty and wonder of the stars, when we look with just our eyes we are seeing and appreciating only a tiny fraction of the Universe. What does the cosmos have in store for us beyond the phenomena we can see, from black holes to supernovas? How different does the invisible Universe look from the home we thought we knew? Dr Matt Bothwell takes us on a journey through the full spectrum of light and beyond, revealing what we have learned about the mysteries of the Universe. This book is a guide to the ninety-nine per cent of cosmic reality we can’t see – the Universe that is hidden, right in front of our eyes. It is also the endpoint of a scientific detective story thousands of years in the telling. It is a tour through our Invisible Universe.

Everybody has one. It’s called a "haunt detector." It’s the little alarm that goes off in our heads whenever we detect that something mysterious or supernatural has occurred. You could be sitting around relaxing one day at home, and for no special reason you start thinking about someone. Maybe you haven’t thought about this person in years. Then the phone rings; you pick it up, and amazingly, it’s that person! Many of us have experienced this phenomenon. What is it? Anthony DeStefano answers this compelling question in his fascinating new book, The Invisible World. No matter how little we may understand or how fleeting such moments can be, he explains the reality of the spiritual dimension that surrounds us and shows how it is immediately accessible to everyone. All aspects of the spiritual realm are discussed, including the existence of angels and demons, the whereabouts of loved ones who have passed, and even the presence and activity of God in our lives. Written to be completely consistent with traditional Christian teaching, The Invisible World will help readers embrace a certitude that makes it easier to act according to their moral beliefs, give them a greater sense of the richness of life, and show them that no amount of suffering in their life—physical, mental, or emotional—will ever be able to destroy the profound sense of inner peace that can be experienced on a daily basis. For those seeking reassurance about meaning in their life, nothing is more significant than to be reminded that no one is alone. In The Invisible World, Anthony DeStefano shows the truth of this in a captivating and inspiring way.

Astronomy, astrophysics and space research have witnessed an explosive development over the last few decades. The new observational potential offered by space stations and the availability of powerful and highly specialized computers have revealed novel aspects of the fascinating realm of galaxies, quasars, stars and planets. The present completely revised 5th edition of The New Cosmos provides ample evidence of these dramatic developments. In a concise presentation, which assumes only a modest prior knowledge of mathematics and physics, the book gives a coherent introduction to the entire field of astronomy and astrophysics. At the same time it takes into account the art of observation and the fundamental ideas behind their interpretation. Like its predecessors, this edition of The New Cosmos will provide new insight and enjoyment not only to students and researchers in the fields of astronomy, physics and earth sciences, but also to a wide range of interested amateurs.
