Inside the depths of planets, where extreme pressures and temperatures reign, matter takes on some truly bizarre forms. While iron atoms are believed to dance within Earth's solid inner core, the gas giants Uranus and Neptune likely host an unusual type of ice, known as superionic ice, which exists as both a solid and a liquid simultaneously. This extraordinary form of ice was first recreated in laboratory experiments five years ago and its existence and crystalline structure were confirmed four years later.
