A Discovery That Might Rewrite the Story of Life As We Know It

Are we on the brink of a discovery that will rewrite the story of life as we know it? "Second Genesis" follows planetary scientist Carolyn Porco as she explores the scientific quest to find life beyond Earth, and makes the case for Saturn’s moon Enceladus — with its plumes of water vapor and evidence of hydrothermal vents in a liquid ocean — as the most promising place to look.

Bigger Than T.rex

Almost a century ago, paleontologists found the first tantalizing hints of a monster even bigger than Tyrannosaurus Rex, perhaps the largest predator ever to walk the Earth: spectacular fossil bones from a dinosaur dubbed Spinosaurus. But the fossils were completely destroyed during a World War II Allied bombing raid, leaving only drawings, lots of questions, and a mystery: What was Spinosaurus? Now, the discovery of new bones in a Moroccan cliff face is reopening the investigation into this epic beast. What did it feed on and how? Why did it grow so big?
