Neptune

Neptune, captured by the Voyager 2 spacecraft. A new study finds a link between the planet's cloud coverage and solar activity.

Neptune's Clouds Have Disappeared, and the Sun Might Be Responsible

Scientists have linked shifts in the distant planet's cloud coverage to the ever-oscillating solar cycle, which is due to peak soon

Why Neptune Appears Bluer Than Its Cousin Uranus

Though the solar system’s two outermost planets are very similar, their color is a puzzling difference

An artist's illustration imagines the newly discovered Farfarout (lower right), now confirmed to be the most distant object ever observed in our solar system. Farfarout is 132 times the distance of Earth to the sun (upper left) and is estimated to be around 250 miles across.

There's a Dark and Stormy Vortex Brewing on Neptune

It is the sixth massive dark and stormy vortex found on the planet since 1989 and the only one astronomers have watched develop
