An Unknown State of Matter Could Be Hiding in Our Solar System

Carnegie Institution researchers used quantum simulations to predict a new carbon-hydrogen state under extreme pressure and heat.

The phase features a helical carbon lattice with hydrogen moving in a superionic, quasi-one-dimensional way.

The finding could help explain the interiors of ice giants like Uranus and Neptune and refine planetary models.

If confirmed, it would expand understanding of matter under extreme planetary conditions.
