Lying at the very outskirts of our solar system, the ice giant Neptune has long represented both a challenge and a mystery to astronomers and space explorers alike. The dark and cold planet, the ...

For decades, Uranus and Neptune have remained among the least understood planets in the solar system. Their distance from ...

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 ...

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 ...

Recent observations of the Kuiper Belt have revealed anomalies that suggest the presence of an undiscovered Neptune-sized planet. This potential celestial body, often referred to as “Planet Y,” could ...

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. Credit: NASA / ESA / M. Showalter / ...

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. When you purchase through links on our ...

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 ...
