Venus as a Potentially Habitable Planet - The Search for Signs of Life

Join MIT Professor Sara Seager for a fascinating physics colloquium exploring Venus as a potentially habitable planet and the controversial detection of phosphine gas that has reignited scientific interest in Earth's neighboring world. Delve into decades-old mysteries surrounding Venus' atmospheric physics and chemistry, particularly focusing on the Earth-like conditions found 48-60 km above the planet's surface in its cloud layers. Learn about the challenges any potential life forms would face, including the need to remain perpetually airborne to avoid scorching temperatures and survive in highly acidic environments. Explore the paradigm shift in understanding organic chemistry within sulfuric acid environments, the significance of phosphine as a potential biosignature gas, and discover the upcoming "Morning Star Missions" designed to definitively answer whether Venus could harbor life. Examine various scientific perspectives on the possibility of life on Venus, from water droplet fragmentation to photochemistry models, while considering the implications for future exoplanet exploration and our understanding of life in the universe.
