Forget the big bang. The real moment of creation was the Cosmic Dawn - the moment of first light. This is the scientific version of the story of Genesis. The big bang gets all the credit for creating our universe. But in fact, the universe it gave was dark and boring. There were no stars, no galaxies, just a vast, black fog of gas - the cosmic dark ages. But, after a hundred million years of nothing, came a dramatic moment of transformation - the Cosmic Dawn. It's the moment the first stars were born, the moment that lit up the Universe, and made the first structure and the first ingredients of life. This was the real moment of creation. Astronomers are now trying to witness the cosmic dawn. For the first time they have the tools to explore the very first stars of the universe and to tell the scientific story of our creation.

Second Genesis follows planetary scientist Carolyn Porco as she explores what it takes to look for life beyond Earth, and what conditions are required for life to exist. Porco makes the case that Saturn’s moon Enceladus—with its plumes of water vapor spewing into space, confirmed organic materials, and evidence of hydrothermal vents at the bottom of its liquid ocean—is the most promising place to look. Could Enceladus be the key to proving once and for all that life is not unique to Earth? And what it would mean—both scientifically, and spiritually—if we found evidence of a true second genesis right here in our own galactic back yard?

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.
