Scientists have detected a giant fan-shaped structure buried beneath the East Antarctic Ice Sheet, suggesting the frozen continent may be hiding the geological scars of the breakup that helped separate Antarctica from Australia
Scientists thought Titan was hiding a global ocean beneath its frozen crust. But a 2025 reanalysis of Cassini data points to something stranger instead — a roughly 380-kilometre-thick layer of slushy ice, close to melting and likely threaded with pockets of liquid water that could reach 20°C near the rocky interior.
In 2007, scientists used NASA satellite measurements to reveal 14 areas of moving water beneath West Antarctica; one hidden lake had drained about 2 cubic kilometres in three years
