Diamonds Are Raining Down On Uranus And Neptune. Here’s How It Works:

It showers diamonds deep beneath Neptune and Uranus, astronomers and physicists have speculated for over 40 years. However, studying our Solar System’s outer planets is difficult. Because just one space mission, Voyager 2, has passed past to expose some of its mysteries, diamond rain has remained a theory. Beyond the remaining mystery of the diamond rain, there is a significant loss in our failure to thoroughly investigate Uranus and Neptune. Because planets of this size are exceedingly numerous in the Milky Way, it restricts our understanding of the Solar System and the galaxy.

The number of planets found in the galaxy that are similar in size to Uranus and Neptune is around nine times more than the number of considerably larger planets identified in the galaxy that are similar in size to Jupiter and Saturn. The scars on the outermost planets appear to teach us a lot about the origin of our own Solar System. As a result, there is an increasing feeling of urgency to examine Neptune and Uranus, both to better understand where and how planetary systems evolve and to improve our notions about where to hunt for planets capable of supporting life.

Although spacecraft and ground-based observatories have limited our ability to learn about the exteriors of Uranus and Neptune, breakthroughs in laboratory simulations are permitting startling new insights into what’s happening in their interiors, including what causes diamond showers. Such discoveries highlight the complexities of the chemical processes involved in the development of these planets. Our simulations provide insights into the inner workings of worlds far beyond the Solar System, including realms that we may never view directly from the outside.

Neptune and Uranus are known as our Solar System’s “ice giants” because their outer two layers are made up of compounds including hydrogen and helium. In astronomical jargon, ice refers to any light element compounds containing hydrogen, therefore the planets’ water (H2O), ammonia (NH3), and methane (CH4) make them “icy.” Both planets’ stunning bluish hues are caused by methane deposits in their atmospheres.
