Quote:Uranus is probably full of giant diamonds
Quote:When subjected to the pressures (and temperatures) of life on other planets, even familiar substances can get pretty alien. Case in point: the diamond rains of the ice giants. Scientists have long thought that massive planets like Neptune and Uranus—which contain relatively tiny rocky cores covered with a mantle of slurried water, ammonia, and methane ices and surrounded by a thick atmosphere—are subject to rain made of literal diamonds. Now researchers have synthesized the process in a lab, showing how such conditions might occur.
