Check Out Neptune’s Beautiful Auroras, Captured for the First Time by the James Webb Space Telescope

Scientists suspected the ice giant hosted auroras—and had already observed them on Jupiter, Saturn and Uranus. But an observation of Neptune’s lights remained elusive for decades

The Six Most Amazing Discoveries We’ve Made About Neptune

Despite the lack of a dedicated mission to the planet, scientists have learned plenty through ground observations and space telescopes

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.
