Lecture: Did Venus Ever Have Oceans?



Often called Earth's twin, there is much debate over Venus' status as a watery world

May 28, 2025. 8:00 p.m. to 9:00 p.m.

Often called Earth's twin, there is much debate over Venus' status as a watery world: If Venus had oceans, where did all that water go? Join Rita Parai from Washington University in St. Louis as she explores the question "Did Venus Ever Have Oceans?" She will also discuss a current mission concept that hopes to return a sample of Venus's atmosphere for analysis here on Earth to further enhance our understanding of the planet Venus.


Rita Parai is an assistant professor of geochemistry at Washington University in St. Louis. Her laboratory for high-precision noble gas isotopic analyses pursues high-precision measurements of isotopes in rocks to better understand the formation and evolution of planetary bodies. 


This program will be presented in-person at the National Air and Space Museum in DC and will be streamed live on the Museum's YouTube channel


ASL interpretation will be provided for the in-person event. ASL interpretation and live captioning will be provided on YouTube. If you require another access service to fully participate or have any questions about accessibility, please contact NASMPublicLectures@si.edu.
