The Hubble Space Telescope has peered at Uranus, left, and Neptune to study the so-called "ice giant" planets, but little is known about their interior composition. - NASA / ESA / M. Showalter / L.

What if our understanding of Uranus and Neptune's compositions have been wrong, specifically regarding their classifications as "ice giants?" This is what a recent study accepted for publication in ...

The interiors of ice giant planets like Uranus and Neptune could be home to a previously unknown state of matter, according to new computational simulations by Carnegie's Cong Liu and Ronald Cohen.

We actually know very little about what's going on inside Uranus and Neptune, causing researchers to propose that these planets be called "rocky giants" instead.

The deep interiors of ice giants such as Uranus and Neptune may contain a previously unknown form of matter, based on new computational research by Carnegie scientists Cong Liu and Ronald Cohen.

A new computational model suggests that Uranus' and Neptune's cores may be less icy than their "ice giant" nickname suggests. When you purchase through links on our site, we may earn an affiliate ...
