Interiors of Neptune and Uranus May See Diamond Rains

Diamond rain, a rare type of precipitation that was once believed to only occur on ice giant planets, may be more prevalent than previously believed.

The presence of oxygen boosts the likelihood of diamond creation, and diamonds can form under low temperatures and pressures,...

according to studies done with material comparable to that found in ice giants like the solar system's Neptune and Uranus.

This implies that diamonds could develop in a variety of environments on these icy planets. This would increase the likelihood of diamond showers pouring through the interiors of ice giants.

The formation of an unusual type of water was also found during the same experiments, which may help explain why Uranus and Neptune's magnetic fields have so far baffled astronomers.

The study may alter our perception of ice giants, which some researchers consider may be one of the most typical types of exoplanets, or planets outside the solar system.

The team of researchers, which included scientists from the Helmholtz-Zentrum Dresden-Rossendorf (HZDR), the University of Rostock, and the SLAC National Accelerator Laboratory...

...relied on earlier studies into the conditions and materials within ice giants that saw diamond rains as they developed.

According to the most recent studies, diamonds in Neptune and Uranus may reach enormous sizes and weigh millions of carats.
