Looking for life in the clouds of Venus

A group of researchers and private investors are planning a series of privately funded missions to Venus, hoping to find signs of life. That may seem like a startling possibility. Although Venus is a close neighbor to Earth, it has a smothering atmosphere of carbon dioxide that has allowed the planet’s surface to heat to temperatures that would melt lead. There’s crushing pressure. And to top it off, there are clouds of sulfuric acid.

Astrophysicist and planetary scientist Sara Seager joins Host Ira Flatow to explain why she thinks life on Venus might be possible, high up in the clouds. Seager has conducted lab experiments that indicate various biomolecules could survive there, despite the toxic conditions. She’s leading a series of proposed private missions to the planet, to study the atmosphere, conduct habitability studies, and even bring back a sample of Venusian cloud material.

Guest:

Dr. Sara Seager is an astrophysicist and a professor of physics, planetary science, and aeronautics and astronautics at the Massachusetts Institute of Technology.
