CAPE CANAVERAL, Fla. (AP) — New research suggests that Titan, Saturn’s massive moon, may not have a hidden ocean after all. Instead, it could be filled with layers of ice and slushy material more like Earth’s polar regions. There might even be pockets of liquid water where life could potentially exist.
A team from NASA’s Jet Propulsion Laboratory revisited data collected by the Cassini spacecraft, which studied Saturn and its moons for years. They now believe that assumptions about a global ocean on Titan may need to be revised. “Nature has shown incredible creativity,” said Baptiste Journaux from the University of Washington, emphasizing that the forms of potential life on Titan could be quite unique.
According to the research, Titan’s icy layers may extend more than 340 miles (550 kilometers) deep. The icy surface could be around 100 miles (170 kilometers) thick, covering a slushy layer that might be home to liquid water, possibly even at temperatures warm enough for life.
Studies also reveal how Titan’s position relative to Saturn affects its shape. The moon is tidally locked, so it always shows the same face to the planet. Saturn’s gravity distorts Titan’s surface, creating noticeable bulges.
The lead researcher, Flavio Petricca, indicated that when they measured the gravitational forces acting on Titan, they found a 15-hour delay in the moon’s surface response. This suggests an interior of slushy ice rather than a full ocean.
Not everyone is convinced. Scientist Luciano Iess, who previously argued for the existence of an ocean, pointed out that more evidence is needed. He believes that Titan still has a chance to be classified as one of the “ocean worlds.”
The upcoming NASA Dragonfly mission will send a helicopter-like craft to Titan later this decade. This mission aims to uncover more about the moon’s interior and potentially give clearer answers about the possibility of life there.
Saturn is known for having the most moons in the solar system, with Titan at the forefront. Other moons, like Jupiter’s Europa and Enceladus, are also considered possible water worlds, generating excitement about the search for extraterrestrial life.
As technology advances, our understanding of these celestial bodies continues to evolve. It’s a reminder of how much mystery still lies in our universe.
