CBS News reported that scientists have discovered that in addition to the three states of gas, liquid and solid water, there is also a “fourth state” called “superionic ice”.

Scientists say that this “strange black ice” usually forms in the cores of planets such as Neptune and Uranus. However, there is also super-ion ice inside the earth, which plays a role in maintaining the magnetic field. Mars and Mercury have no magnetic field protection, and the weather is bad. Scientists believe that searching for superionic ice may play a role in searching for other habitable planets.

“Nature – Physics” journal (Nature Physics) published a study wrote, Jia Zhi Columbia professor Plaka Penca (Vitali Prakapenka) co-led the research team in detail, the ice must be super ion to form under extreme conditions . Scientists previously used a huge shock wave to penetrate the water droplets before they were able to see the true appearance of super-ion ice for a moment.

This time, the research team used a different method to reproduce the super-ionized ice. They used two diamonds to squeeze the water to reproduce the huge pressure environment of the planet’s core, and used scientific research tools Advanced Photon Source (APS) and high-brightness X-rays to heat the water. The research team later discovered that the density of superionic ice is not so high, and because of its different interaction with light, it looks black.

Praka Penka said: “This is a new state of matter, so it is basically a new material, which may be different from what we imagined.”

Scientists are even more surprised that the pressure required to form superionic ice is much lighter than they thought. They originally thought that it would take 50 gigapascals (gigapascals) to form superionic ice, which is equivalent to the pressure required for the fuel inside the rocket to burn and lift off, but in fact it only needs 20 gigapascals.
