PARIS - It could be raining diamonds on planets throughout the universe, scientists suggested Friday, after using common plastic to recreate the strange precipitation believed to form deep inside Uranus and Neptune. Scientists had previously theorised that extremely high pressure and temperatures turn hydrogen and carbon into solid diamonds thousands of kilometres below the surface of the ice giants. Now new research, published in Science Advances, inserted oxygen into the mix, finding that "diamond rain" could be more common than thought.
