Researchers at KRISS observed water’s rapid freeze–melt cycles under ultrahigh pressure and discovered Ice XXI, the first new ice phase found in decades. Using advanced high-pressure tech and ...

Cryovolcanic activity on icy satellites arises when internal heating—driven by tidal flexing, radiogenic decay or residual accretional heat—melts or dissolves volatile constituents (water, ammonia or ...

Sky watchers will be getting a double lunar treat in May 2026, with two full moons set to glow in the night sky during the same calendar month. The so-called “flower moon” will be turning full on May ...
