With the development of space-travel, we have begun to explore worlds beyond Earth. Ten planetary scientists have come together to describe their favourite planet, what they have discovered, and what drives them to explore. Each tells a personal story, ranging across the breadth of the solar system - from hellish Mercury to the snows of Pluto; from telescopic to robotic exploration; from adventures in Antarctica to painting planetary landscapes; from the frustrations of failure to the joys of success. Worlds Beyond is the third in a series of extraordinary books bringing together leading space scientists to describe their work. Our Worlds was the first of its kind in revealing the inner motivations of planetary scientists. In Our Universe, leading astronomers and cosmologists explored the vastness of the Universe itself. Now with Worlds Beyond we return to our home - the solar system - to visit those fascinating new worlds beyond our own.
