Pulsars are rapidly spinning neutron stars, the collapsed cores of once massive stars that ended their lives as supernova explosions. Pulsar rotation rates can reach incredible speeds, up to hundreds of times per second. The story of how an object spins up to a significant fraction of the speed of light is fascinating and involves collapsing stellar cores following supernova explosions, while the faster ones result from stellar cannibalism.

In this book, Geoff McNamara explores the history, subsequent discovery and contemporary research into pulsar astronomy. The story of pulsars is...

The dark matter problem is one of the most fundamental and profoundly difficult problems in the history of science. Not knowing what makes up most of the mass in the Universe goes to the heart of our understanding of the Universe and our place in it. In Search of Dark Matter is the story of the emergence of the dark matter problem, from the initial 'discovery' of dark matter by Jan Oort to contemporary explanations for the nature of dark matter and its role in the origin and evolution of the Universe.

Written for the intelligent non-scientist and scientist alike, it spans a variety...

Most people live and work entirely oblivious to the fact that a myriad of ghostly ripples are passing through them all the time. Generated in the depths of space by colliding stars and black holes, exploding supernovas and quasars, these so-called gravitational waves are literally ripples in the fabric of space itself. Sweeping across the cosmos at the speed of light, they encode vital clues about the exotic systems that produced them. Predicted by Einstein over eighty years ago, but never detected in the laboratory, gravitational waves have proven elusive to scientists. In the first book for...
