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 ...

Chinese scientists propose 2033 Neptune orbiter mission Scientists are proposing China’s first ice giant mission, aiming to ...

Since colder temperatures lead to fainter auroral activity, that likely explains why it’s been so difficult to spot Neptune’s auroras—but it doesn’t explain why the ice giant cooled so ...

As reported by NASA Science, Webb’s near-infrared instruments have confirmed the existence of these ghostly lights and opened a new window into the ice giant’s strange magnetic world.

A new study shows Neptune's white clouds have all but vanished - and it may be due to intense ultraviolet (UV) light from the sun, according to scientists at the University of California, Berkeley.

Four years ago, astronomers noticed the abundant clouds on Neptune had largely disappeared. Telescope data may have helped researchers figure out why.

The detection of Neptune's auroras will help astronomers better understand how particles from the sun interact with its atmosphere, providing a new area of study about ice giant planets.
