Diamond Rain In Saturn

Taco Cowboy writes "Back in 1999, it was postulated that diamonds may rain from the sky in the atmospheres of our solar system's gas giants. Now, research has shown that diamond rains on Saturn are more than probable. '"We don't want to give people the impression that we have a Titanic-sized diamondberg floating around," said researcher Mona Delitsky, of California Specialty Engineering, "We're thinking they're more like something you can hold in your hand." Recent data compiled by planetary scientists ... has been combined with newly published pressure temperature diagrams of Jupiter and Saturn. These diagrams, known as adiabats, allow researchers to decipher at what interior level that diamond would become stable. They also allow for calculations at lower levels – regions where both temperature and pressure are so concentrated that diamond becomes a liquid. Imagine diamond rain or rivulets of pure gemstone.' 'At even greater depths, the scientists say the diamond will eventually melt to form liquid diamond, which may then form a stable ocean layer.'

Saturn and Jupiter are also thought to have rocky cores, or to have had them originally, but it is uncertain.

Speaking of which...

    It turns out that the liquid state of carbon is mostly an unknown due to the temperatures and pressures required, but there's been a recent consensus that it acts very differently at "low" and high pressures. Computer simulations and experiments have suggested that under high pressures, carbon orders itself into an irregular but still recognizably diamond-like structure with four neighbors for each atom. In fact, high pressures make the formation of solid diamond when the liquid cools more likely as a result. At low pressures, it's more like graphene or strings of carbon, with bonding to neighbors in 2's & 3's instead of 4's. At even higher pressures it develops into a metallic structure. So the term "liquid diamond" actually has significant meaning and isn't just media buzzwords.
