Planetary atmospheres are complex and evolving entities, as mankind is rapidly coming to realise whilst attempting to understand, forecast and mitigate human-induced climate change. In the Solar System, our neighbours Venus and Mars provide striking examples of two endpoints of planetary evolution: the runaway greenhouse effect and the loss of the entire atmosphere to space.

This book provides a comprehensive, authoritative and timely review of the astrophysical approach to the investigation of gravity theories. Particular attention is paid to strong-field tests of general relativity and alternative theories of gravity, performed using collapsed objects (neutron stars, black holes and white dwarfs) in relativistic binaries as laboratories.
The book starts with an introduction [...]

Astronomy is advancing at an unprecedented rate, and there have never before been so many backyard astronomers, from beginners to those at the professional frontier. There is also huge interest in the startlingly imaginative concepts that professional astronomers use to explain our place, and existence, in the universe at large.

Even though everyone can enjoy the sight from a suitably dark location, it is poorly understood, and has been the subject of relatively little research. Brian May began his [...]

Astronomy is facing a paradigm shift. The huge quantities of data that are being created by a new generation of surveys and instruments will require new ways of thinking. At the same time, an ever-more connected world is bringing astronomy to the masses via new media, comprising blogs, podcasts, social networks, and more.

Once we thought the universe was filled with shining stars, dust, planets, and galaxies. We now know that more than 98 percent of all matter in the universe is dark. It emits absolutely nothing yet bends space and time; keeps stars speeding around galaxies; and determines the fate of the universe.
But dark matter is only [...]
