When you believe of ice, you almost certainly photograph the cubes in your freezer, or maybe an iceberg or frozen pond. But ice can choose all varieties of diverse kinds, and not too long ago a group of researchers managed to recreate one particular of the most exotic forms of ice in their lab, thanks to a assortment of tremendous-powered lasers.

The type of ice we’re most familiar with is a distinct kind identified as Ice I. Ice has almost two dozen other sorts, like Ice II, which sorts when you get started making use of pressure to normal ice. With more strain you’d get Ice XV, then Ice VIII, then Ice X, and so on. You could locate even additional distinctive varieties of ice at various pressures and temperatures, and these permutations have distinctive appearances and attributes.

So to locate some of the far more unique varieties of ice, researchers at the Lawrence Livermore Countrywide Laboratory in California built a incredibly complicated experiment: They would trap water within a tightly confined area and blast it with large-powered lasers. All alongside one another, the scientists made use of 6 lasers at the University of Rochester’s Laboratory for Laser Energetics to get the occupation accomplished.

In only a fraction of a next, these lasers heated the h2o droplet to all around 4,000 levels Fahrenheit and compressed it to about a million occasions the force of the Earth’s environment. The final result created a one of a kind compound that the scientists are contacting Ice XVIII.

Ice XVIII exists nowhere on Earth—except incredibly briefly in that lab in Rochester—but experts suspect it may possibly be equipped to type on huge icy planets like Uranus and Neptune. These planets are built up largely of drinking water, and because of to their dimensions, they could probably reach the identical sorts of temperatures and pressures the LLNL scientists attained in their lab.

If that’s the case—and it really very likely is—then this experiment can support us understand additional about Uranus, Neptune, and other gas giant planets in our galaxy. Many thanks to the exam, researchers will have a substantially superior understanding of what Ice XVIII appears to be like and how it behaves.

It is achievable the research could resolve some mysteries bordering these planets’ magnetic fields. The two Uranus and Neptune have unconventional magnetic fields—Uranus’ area is totally upside down, for example—and some of that unconventional actions could be defined by Ice XVIII. If Uranus and Neptune have a substantial excellent of this sort of ice buried someplace under the surface, that could impact their magnetic fields.
