Io is one of the large satellites of Jupiter. A little larger than Earth’s Moon, it is intensely volcanic as a result of extreme tidal heating. Typically, a half-dozen or more volcanoes are erupting every day on Io. NASA’s Juno spacecraft, in polar orbit around Jupiter since 2016, has provided unprecedented views of Io’s poles, allowing a full, global accounting of Io’s extraordinary volcanoes for the first time. Dr. Davies will talk about the latest observations of Io by Juno and the James Webb Space Telescope, and what these data have revealed about Io’s volcanoes and interior.

The event, cosponsored by NASA's Missouri Space Grant Consortium, is open to the public free of charge.​​​​​​ The St. Louis Astronomical Society is an organization for individuals interested in astronomy and telescopes.

Free parking will be available.
