Dr. Jennifer Meyer, visiting assistant professor of physics and astronomy at the University of Mississippi will present: "Tides on Enceladus"

Enceladus, a small moon of Saturn, has a surface temperature of -200°C (-330°F). Surprisingly, in 2005, the Cassini mission found evidence that this seemingly frigid moon has liquid water under the surface - and jetting out from the surface in geysers more active than any on Earth. If Enceladus was warmed by sunlight only, the moon would be solid ice. The most likely source of the energy powering the geysers and maintaining the subsurface ocean is tidal heating, but scientists are still working on making the numbers add up. In this talk, we'll learn how tides affect the geology and orbit of moons like Enceladus and discuss why Enceladus is one of NASA's prime spots to look for life.
