Cahill, Hameetman Auditorium
The Solar System's Volcanic Wonderland
Katherine de Kleer, Assistant Professor, Department of Geological & Planetary Sciences, Caltech,
  • Public Event

Jupiter's moon Io is covered with active volcanoes, many of them significantly more powerful than anything on Earth today. From lava lakes and lava fountains to massive umbrella plumes, Io's volcanic features span a wide spectrum of styles and give us information about this moon's interior. Telescope technologies allow us to watch volcanoes erupt on Io from telescopes on Earth, and such observations have led to recent breakthroughs in our understanding of this exotic world. This talk will present discoveries from such observations, and from spacecraft visits to Io over the past 20 years, and will discuss new mysteries that these discoveries have uncovered.

About the Series

Stargazing Lectures are free lectures at a public level followed by a Q&A panel and guided stargazing with telescopes (weather permitting). All events are held at the Cahill Center for Astronomy and Astrophysics at Caltech. No reservations are needed. Lectures are 30 minutes; stargazing and panel Q&A last 90 minutes. Stay only as long as you want.

Stargazing is only possible with clear skies, but the lecture and panel Q&A takes place regardless of weather.
