So far, humanity has yet to find its first "exomoon"—a moon orbiting a planet outside of the solar system. But that hasn't ...

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.

Scientists may have missed the mark when they started referring to Uranus and Neptune as the "ice giant" planets of the solar system decades ago. Like giving a certain short-armed dinosaur a name that ...

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 ...

Studying the orbits of thousands of exoplanets shows that large planets tend to have elliptical orbits, while smaller planets tend to have more circular orbits. This split coincides with several other ...

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 ...
