Venus: Death of a Planet

Billions of years ago, Venus may have harbored life-giving habitats similar to those on the early Earth. Today, Earth's twin is a planet knocked upside down and turned inside out. Its burned-out surface is a global fossil of volcanic destruction, shrouded in a dense, toxic atmosphere. Scientists are now unveiling daring new strategies to search for clues from a time when the planet was alive.
