A new model of Uranus's interior proposes a thermal boundary layer within its mantle, potentially explaining its unexpectedly low luminosity compared to Neptune. This model incorporates a rockier ...

Scientists have identified a new "superionic" state of carbon and hydrogen that may exist deep inside Uranus and Neptune.

For decades, Uranus and Neptune have been filed neatly into the “ice giant” drawer, shorthand for worlds built mostly from frozen water, ammonia and methane wrapped in hydrogen and helium. A new ...

Uranus and Neptune have been called the “ice giants” for decades. But in new research, that nickname might be more a misnomer than anything. A study by the lead researchers astrophysicists Luca Morf ...

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.

The strikingly low luminosity of Uranus (Teff ~ Teq) constitutes a long-standing challenge to our understanding of Ice Giant planets. Here we present the first Uranus structure and evolution models ...

Under the ice: Models for the interior structures of the ice-giant planets Uranus and Neptune have two distinct, intermediate layers: an upper, water-rich convecting layer where disorganized magnetic ...

Models for the interior structures of the ice-giant planets Uranus and Neptune have two distinct, intermediate layers: an upper, water-rich convecting layer where disorganized magnetic fields are ...

Because Uranus and Neptune are so far away, scientists only have educated guesses about the combination of ices and gases that make up these ice giants. While the general understanding is that these ...

We’ve got a pretty good idea about what’s beneath the surface of our nearest planetary neighbors, like Mars. But as you get farther out into the solar system, our knowledge becomes scarce. For ...

Models for the interior structures of the ice-giant planets Uranus and Neptune have two distinct, intermediate layers: an upper, water-rich convecting layer where disorganized magnetic fields are ...

Add Yahoo as a preferred source to see more of our stories on Google. NASA's James Webb Space Telescope has captured the first vertical view of Uranus's upper atmosphere, delivering an unprecedented ...
