science ๐ฐ๏ธ Titan's ocean theory might be off
Scientists are rethinking the long-held belief that Saturn's moon Titan has a global ocean under its icy shell. A 2025 paper in Nature reanalyzed Cassini's radio data, suggesting the interior is likely mostly slushy ice. This new study found Titan dissipating significant energy, which a global ocean model could not explain. Instead, the data supports a thick, high-pressure ice layer with pockets of liquid water. Future missions like Dragonfly could help confirm this new model of Titan's interior. ๐ง
