For decades, Uranus and Neptune have been filed neatly into the “ice giant” drawer, shorthand for worlds built mostly from ...

A new computational model suggests that Uranus' and Neptune's cores may be less icy than their "ice giant" nickname suggests.

New models suggest Uranus and Neptune may hold far more rock than expected, raising questions about how these distant planets formed.

Giant planets like Uranus and Neptune may contain much less free hydrogen than previously assumed. Researchers from the German Helmholtz-Zentrum Dresden-Rossendorf (HZDR) drove shock waves through two ...

It's a bit mind-boggling to imagine something as big as the planet Neptune crashing into a similar-sized planet, but astronomers caught this exact scenario, as described in a recent study in the ...

The ice-giant Neptune, the most distant and third largest planet in our solar system, is a distinctive dark blue ball of gas, which may appear calm but is actually throttled by a chaotic atmosphere.

Based on new simulations, scientists believe that giant gas planets across the universe can often collide and merge into even bigger gas plants — behemoths called "super-Jupiters." In the cosmic ...

Images taken by the Hubble Space Telescope document the formation of a Great Dark Spot on Neptune for the first time, report researchers in a new study. Like Jupiter’s Great Red Spot, Neptune’s Great ...
