OXFORD, Miss. \u2013 The surprising discovery of liquid water on one of Saturn’s moons is the topic for a monthly public science forum organized by the University of Mississippi Department of Physics and Astronomy<\/a>.<\/p>\n

The fall semester’s first meeting of the Oxford Science Cafe is set for 6 p.m. Tuesday (Sept. 18) at its new location of Uptown Coffee, 265 North Lamar Blvd. Jennifer Meyer, visiting assistant professor of physics and astronomy, will discuss “Tides on Enceladus.” Admission to the event is free.<\/p>\n

The Oxford Science Cafe features monthly conversation about science known and unknown. Speakers and topics are scheduled through the Department of Physics and Astronomy.<\/p>\n

“This is the first meeting at Uptown Coffee,” said Marco Cavaglia, professor of physics and astronomy. “We are very thankful to Uptown Coffee’s owners for sponsoring the Oxford Science Cafe. We hope to have many more meetings there.”<\/p>\n

“Enceladus, a small moon of Saturn, has a surface temperature of minus 200 degrees C, or minus 330 degrees F,” Meyer said. “Surprisingly, in 2005, the Cassini mission found evidence that this seemingly frigid moon has liquid water under the surface \u2013 and jetting out from the surface in geysers more active than any on Earth.”<\/p>\n

Meyer’s 45-minute presentation will include discussion about how tides impact the geology and orbit of moons such as Enceladus. She also will discuss why Enceladus is one of NASA’s prime spots to look for life.<\/p>\n

“If Enceladus was warmed by sunlight only, the moon would be solid ice,” she said. “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.”<\/p>\n

Cavgalia said Meyer’s appearance should be most interesting.<\/p>\n

“Dr. Meyer is an expert in lunar explorations within our solar system,” he said. “Her presentation is sure to be fascinating and enlightening.”<\/p>\n

Meyer earned her doctorate in planetary science from the Massachusetts Institute of Technology.<\/p>\n
