Copernicus sowed the seed from which science has grown to be a dominant aspect of modern culture, fundamental in shaping our understanding of the workings of the cosmos. John Henry reveals why Copernicus was led to such a seemingly outrageous and implausible idea as a swiftly moving Earth.

Humanity has always looked to the stars, but it hasn't been until relatively recently that we have managed to travel into space. Carolyn Collins Petersen takes us on a journey from the first space pioneers and their work, through the First World War-led technological advances in rocketry that formed the basis for the Space Age, to the increasing corporate interest in space. This detailed examination of our steps into space is viewed from our potential future there - on Mars to be exact - and considers how we will reach that point. The author concludes with our current advances and our immediate ambitions in space exploration. The future and its scientific possibilities are enthralling: who will be the first to step on Mars? Will matter/antimatter annihilations take us to the Kuiper Belt, or will it be ion propulsion? What is the Alcubierre Warp Drive? Will it take us to the stars?

As end-of-the-world scenarios go, an apocalyptic collision with an asteroid or comet is the new kid on the block, gaining respectability only in the last decade of the 20th century with the realisation that the dinosaurs had been wiped out by just such an impact.

Now the science community is making up for lost time, with worldwide efforts to track the thousands of potentially hazardous near-Earth objects, and plans for high-tech hardware that could deflect an incoming object from a collision course – a procedure depicted, with little regard for scientific accuracy, in several Hollywood movies.

Astrophysicist and science writer Andrew May disentangles fact from fiction in this fast-moving and entertaining account, covering the nature and history of comets and asteroids, the reason why some orbits are more hazardous than others, the devastating local and global effects that an impact event would produce, and – more optimistically – the way future space missions could avert a catastrophe.
