Consider this your daily reminder that the solar system is even more awesomely bonkers than you realized: On Uranus and Neptune, scientists forecast rain storms of solid diamonds.
The gems form in the hydrocarbon-rich oceans of slush that swath the gas giants' solid cores. Scientists have long speculated that the extreme pressures in this region might split those molecules into atoms of hydrogen and carbon, the latter of which then crystallize to form diamonds. These diamonds were thought to sink like rain through the ocean until they hit the solid core.
But no one could prove that this would really work until now. In a study published this week in the journal Nature Astrophysics, researchers say they were able to produce this "diamond rain" using fancy plastic and high-powered lasers.
The results will be useful not just for understanding the outer gas giants but for improving the process of making diamonds. Most lab-grown stones are produced via a blasting process, but Kraus and Gericke suggest that using lasers may make production cleaner and easier to control. Those stones can then be used for semiconductors, drill bits and solar panels, not to mention instruments that mimic the conditions inside the very gas planets that inspired this research.
