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
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.
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
