A Talk by Dr. Oliver White (SETI Institute) May 28, 2025 Ten years ago, the New Horizons spacecraft flew by the Pluto system and revealed an unexpectedly diverse range of landscapes on that dwarf planet and its largest moon Charon -- implying much more complex geological histories for these distant worlds than anyone expected. Dr. White leads a vivid tour of their often bizarre terrains, some of which are still evolving, and explains what processes scientists think molded them into their pres...

New Worlds: Analyzing the Atmospheres of Exoplanets with the James Webb Space Telescope
Non-technical Talk by Prof. Jonathan Fortney (U. of California, Santa Cruz) Apr. 9, 2025 Over 6000 planets have now been found around other stars, but we only have information about what their atmospheres are like for a few dozen. NASA's powerful James Webb Space Telescope (JWST), which features a 20-foot mirror in space, is currently being used to understand planetary atmospheres. Prof. Fortney explains how we can look for atmospheres around rocky planets the size of the E...
