Researchers have synthesized millimetre-scale hexagonal diamond, a crystal structure so elusive that many physicists doubted it could ever be produced in bulk. The material, also called lonsdaleite, ...

The long-lived international Cassini mission has revealed a surprising feature emerging at Saturn's northern pole as it nears summertime: a warming, high-altitude vortex with a hexagonal shape, akin ...

Scientists have used a mix of physical and chemical properties to bend salt into hexagonal crystals for the first time ever. They formed the thin layer of crystalline salt on a substrate (foundation ...

Sitting atop Saturn’s north pole is one of the Solar System’s most striking weather patterns: a rotating, color-changing hexagon slightly wider than Earth. A new study shows there’s another hexagon ...
