"Neptune was the missing piece of the puzzle when it came to detecting auroras on the giant planets," said the European Space ...

The most elusive planetary aurora in the Solar System has finally been revealed in all its gently glowing glory.

When NASA’s Voyager 2 mission flew by Neptune in 1989, it found tantalising hints of aurora activity in the ice giant’s clouds. However, scientists were unable to verify the phenomenon at the ...

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 ...

For the first time, the James Webb Space Telescope (JSWT) has revealed bright auroral activity on the planet Neptune. Capturing the auroral activity on the ice giant has been long in coming ...

This significant achievement sheds light on the elusive auroras of the ice giant, which have long ... appeared as cyan splotches across Neptune's surface. Interestingly, Neptune's auroras differ ...

a totally new window in ice giant atmospheric science. From the Webb observations, the team also measured the temperature of the top of Neptune's atmosphere for the first time since Voyager 2's flyby.

Katy is Managing Editor at IFLScience where she oversees editorial content from News articles to Features, and even occasionally writes some. Thirty-six years after the first hints of auroral ...

Despite its extremely cold atmosphere, the interior of Neptune is far hotter than that of its ice giant twin, Uranus. In fact, Neptune gives out 2.6 times more heat than it receives from the Sun. The ...

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.

But Webb's observations didn't just provide new pretty pictures of the ice giant planet's greenish-blue splotches. It revealed how odd Neptune's auroras are compared to other planets', glowing ...
