The next stop on our virtual tour is Venus, the closest planet to Earth and the hottest planet in our solar system, with surface temperatures scorching enough to melt lead.

NASA’s Jim Green is joined by David Grinspoon of the Planetary Science Institute to discuss Venus’ volcanoes, clouds of sulfuric acid, and runaway greenhouse effect. Was Venus once was like Earth in its distant past and what clues might it provide about the future of our own planet? You’ll also hear about Venus’ backward rotation and “forever sunsets,” plus the remarkable and heroic “Apollo 11”-like story of the Akatsuki spacecraft.
