Description


The Habitability of Venus's Clouds: Following Chemical Clues to Possible Life. Dr. David Grinspoon (Planetary Science Institute) and Dr. David Livingston (The Space Show) discuss the growing mainstream focus on the potential for life in the clouds of Venus. Although the surface is too extreme, the cloud layer provides a relatively benign environment with low pressure and cool temperatures, prompting questions about potential habitability. Life might have migrated to the clouds if Venus lost its ancient, biologically promising oceans. The controversial detection of phosphine, a chemical largely produced by life on Earth, serves as an intriguing, strange chemical clue suggesting something "weird" is happening. Grinspoon also addresses panspermia, noting that hardy organisms like tardigrades could potentially survive natural transfers between planets or even interstellar journeys. The ideal altitude, or "sweet spot," for possible life is around 50 kilometers, where conditions resemble Earth's surface.
