''So staggering you go ''whoa!'' every few seconds'' Guardian ''Really impressive'' Eamonn Holmes, ITV This Morning A companion book to the critically acclaimed BBC series. The bestselling authors of Wonders of the Universe are back with another blockbuster, a groundbreaking exploration of our Solar System as it has never been seen before. Mercury, a lifeless victim of the Sun''s expanding power. Venus, once thought to be lush and fertile, now known to be trapped within a toxic and boiling atmosphere. Mars, the red planet, doomed by the loss of its atmosphere. Jupiter, twice the size of all the other planets combined, but insubstantial. Saturn, a stunning celestial beauty, the jewel of our Solar System. Uranus, the sideways planet and the first ice giant. Neptune, dark, cold and whipped by supersonic winds. Pluto, the dwarf planet, a frozen rock. Andrew Cohen and Professor Brian Cox take readers on a voyage of discovery, from the fiery heart of our Solar System, to its mysterious outer reaches. They touch on the latest discoveries that have expanded our knowledge of the planets, their moons and how they come to be, alongside recent stunning and mind-boggling NASA photography.

A Brief History of Time for the 21st Century At the heart of our galaxy lies a monster so deadly, not even light can escape its grasp. Its secrets lie waiting to be discovered. It''s time to explore our universe''s most mysterious inhabitants Black Holes At the heart of the Milky Way lies a supermassive black hole 4 million times more massive than our Sun. A place where space and time are so warped that light is trapped if it ventures within 12 million km. According to Einstein, inside lies the end of time. According to 21st-century physics, the reality may be far more bizarre.
Black holes lie where the most massive stars used to shine and at the edge of our current understanding. They are naturally occurring objects, the inevitable creations of gravity when too much matter collapses into not enough space. And yet, although the laws of nature predict them, they fail fully to describe them.
Black holes are places in space and time where the laws of gravity, quantum physics and thermodynamics collide. Originally thought to be so intellectually troubling that they simply could not exist, it is only in the past few years that we have begun to glimpse a new synthesis; a deep connection between gravity and quantum information theory that describes a holographic universe in which space and time emerge from a network of quantum bits, and wormholes span the void.
In this groundbreaking book, Professor Brian Cox and Professor Jeff Forshaw take you to the edge of our understanding of black holes; a scientific journey to the research frontier spanning a century of physics, from Einstein to Hawking and beyond, that ends with the startling conclusion that our world may operate like a giant quantum computer.
