The Planets Where Diamonds Rain from the Sky

Deep inside Uranus and Neptune, scientists believe extreme pressure and temperature may transform carbon from methane and other hydrocarbons into solid diamonds. These diamonds would then sink slowly toward the planets’ cores, creating a bizarre phenomenon known as “diamond rain.” This rain would not fall on the surface like ordinary rain on Earth. It would form thousands of kilometers beneath the clouds, inside the dense interiors of these icy giant planets. Laboratory experiments have recreated similar conditions and observed tiny diamonds forming under extreme pressure #DiamondRainNeptuneUranusSpaceFactsAstronomyScienceFactsSolarSystemUniversePlanetFacts
