Scientists melted a diamond and cracked a secret of ice giants

Some of the strangest weather in the solar system doesn’t happen on Earth or even in Jupiter’s Great Red Spot—it happens in the interiors of ice giants like Neptune and Uranus. Specifically, scientists have long believed that, at certain pressures and temperatures, it literally rains diamonds inside these planets. For the first time, scientists have mimicked the process they believe creates this phenomenon.

A new paper by physicists at Lawrence Livermore National Laboratory (LLNL), published in Nature Physics, resolves the 20-year-old scientific mystery and shows how the same physics that makes it rain diamonds inside Neptune could also help us triple our fusion energy output.

Let’s talk about the actual experiment first...

A bizarre new state of matter may be hiding inside Uranus and Neptune

Deep inside planets like Uranus and Neptune, scientists may have uncovered a bizarre new state of matter where atoms behave in unexpected ways. Advanced simulations suggest that carbon and hydrogen, under crushing pressures and scorching temperatures, can form a strange hybrid phase—part solid, part fluid—where hydrogen atoms spiral through a rigid carbon framework. This unusual “superionic” structure could reshape how heat and electricity flow inside these distant worlds, potentially helping explain their mysterious magnetic fields.

The deep interiors of ice giant planets such as Uranus and Neptune may contain a previously unknown form of matter. This possibility comes from new computer simulations conducted by Carnegie scientists Cong Liu and Ronald Cohen.

Their study,...

Uranus and Neptune are hiding something big beneath the blue

Uranus and Neptune may not be the icy worlds we’ve long imagined. A new Swiss-led study uses innovative hybrid modeling to reveal that these planets could just as easily be dominated by rock as by water-rich ices. The findings also help explain their bizarre, multi-poled magnetic fields and open the door to a wider range of possible interior structures. But major uncertainties remain, and only future space missions will The Solar System is commonly grouped by planetary composition: four rocky terrestrial planets (Mercury, Venus, Earth and Mars), two massive gas giants (Jupiter and Saturn), and a pair of ice giants (Uranus and Neptune)...

Mysterious object found dancing with Neptune

A team of astronomers led by the Center for Astrophysics | Harvard & Smithsonian has discovered a rare object far beyond Neptune, from a class known as trans-Neptunian objects, that is moving in rhythm with the giant planet. This image shows the orbits of all of the objects discovered in the Outer Solar System Origins Survey. The orbit of 2020 VN40 is the thickest one, tilted up and to the left from the orbits of most of the objects.  The orbits of the giant planets Jupiter, Saturn, Uranus, and Neptune are the white circles.

This object, called 2020 VN40, is the first confirmed body that orbits the sun once for every ten orbits Neptune completes.

Astronomers have discovered a bizarre object in the outer solar system, 2020 VN40, that dances to Neptune’s g...
