Scientists think it rains diamonds inside Saturn, with roughly 1,000 tons forming each year as lightning storms shatter methane into carbon soot, which the planet's crushing pressure compresses into gems before they sink toward a possible ocean of liquid diamond at the core

Under our feet, at a depth where common sense evaporates and the rock becomes incandescent, the Earth hides a fascinating geological cuisine. If you look mentally at the Earth's mantle, more than one hundred and fifty kilometers from the surface, you find a stage where pure carbon, the same simple element of ...

Scientists think it rains diamonds inside Saturn, with roughly 1,000 tons forming each year as lightning storms shatter methane into carbon soot, which the planet's crushing pressure compresses into gems before they sink toward a possible ocean of liquid diamond at the core
The idea that it rains diamonds inside Saturn is a model of an inaccessible planetary interior, not an observation. No camera has seen the gems and no probe has sampled the depths at which they might form. The model begins with something Cassini did observe: powerful lightning and unusually dark storm clouds. It then combines atmospheric chemistry with laboratory measurements and calculations of how carbon behaves under rising pressure and tempe…
