With his trademark wit, Richard Hammond takes on the ultimate engineering project: how on earth do you build a planet that is just right for life? What do you need to build a planet like ours, and what happens if you get anything wrong? With eye-popping graphics, Richard Hammond opens up a cosmic toolbox to work it out. He's going to build the whole thing, piece by piece, from the top of a two-mile high tower in the Californian desert.

In the Orion constellation, Betelgeuse, a red star 1,000 times the size of the Sun, is an old star that scientists predict will soon come to a violent end. Will we see a supernova explosion 100 times brighter than a full moon in our lifetimes? Will the explosion release rays harming life on Earth?

Four astronomers celebrate 50 years of work and friendship by going on a road trip to revisit some of the world's greatest observatories. In California, a world leader in observational astronomy at a time when America's space programme was at its height, the astronomers spent their formative years developing friendships that would last a lifetime, and making scientific discoveries that would change the course of history. Together they represent the most productive period astronomy has ever had. Their journey through the southwestern United States allows them to see once again the places and landscape they explored as young men. Now in their 70s, they share their reflections on a life spent looking at the universe. Star Men celebrates the history of stargazing: the inventions and discoveries that have enabled us to learn so much about the universe, but more importantly to understand how much more we have yet to discover.

Artificial selection is one example, eyes another, of the well-documented and inescapable process of evolution--change in a population of species over time--by natural selection. These are some of the things that molecules do.

The first close-up images of Pluto revealed unimaginable secrets of this mysterious frozen world. Now, scientists investigate if Pluto is home to a warm ocean of liquid water beneath its surface, and whether this underground ocean could harbour life.
