Using Webb’s near-infrared spectrograph, astronomers have captured new images of Neptune that finally reveal the planet’s mysterious auroral activity. Faint hints of Neptune’s auroras were first ...

‘It was a long-running saga, but what excites me is trying to figure out what it is that makes temperature change in the upper atmosphere of Neptune,’ he said. Dr O’Donoghue ...

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

A Southwest Research Institute-led study modeled the chemistry of TOI-270 d, an exoplanet between Earth and Neptune in size, ...

The photo at left is an enhanced-color image of Neptune from the Hubble Space Telescope. At the right, that image is combined with one from the James Webb Space Telescope that shows greenish splotches ...

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, even ...

So why did it take so long to find them? Turns out the Webb telescope revealed something unexpected: Neptune’s upper atmosphere has cooled significantly over the past few decades—from about ...
