Titan's Slushy Interior Challenges Ocean Theory

New research, led by Flavio Petricca of United States — Jet Propulsion Laboratory and co-authored by Baptiste Journaux of University of Washington, challenges the decade-long assumption that Saturn's moon Titan harbors a vast underground ocean. A reanalysis of data from United States — NASA's Cassini–Huygens spacecraft suggests that Titan instead has deep layers of ice and slush, with pockets of melted water. This slushy interior explains a 15-hour delay detected between Saturn's gravitational pull and the deformation of Titan's surface. While Luciano Iess of Sapienza University of Rome remains unconvinced, the findings, published in Nature (journal), have significant implications for the search for extraterrestrial life, as these pockets of water could be habitable. United States — NASA's upcoming Dragonfly (disambiguation) mission is expected to provide further insights.
