Titan likely has no global ocean; instead, it has a slushy interior with pockets of warm water, according to a new NASA study.
A new NASA-led study reanalyzing Cassini spacecraft data suggests Saturn’s moon Titan likely lacks a global subsurface ocean, instead featuring a slushy interior with pockets of liquid water beneath its icy crust.
Evidence from a 15-hour delay in Titan’s surface response to Saturn’s gravity indicates a rigid, viscous interior rather than a free-flowing ocean, pointing to layers of ice and meltwater.
While no global ocean is confirmed, isolated pockets of warm water—possibly up to 20°C—may exist, offering potential habitats for microbial life.
The findings, published in Nature, challenge long-held assumptions and could reshape understanding of icy moons.
NASA’s Dragonfly mission, set to launch in the 2020s, will explore Titan’s surface and subsurface, providing the first direct test of this new model.
Titan probablemente no tiene un océano global; en cambio, tiene un interior fangoso con bolsas de agua cálida, según un nuevo estudio de la NASA.
