NASA’s Voyager 2 spacecraft found hints of auroras on Neptune in 1989, but scientists couldn’t get a clear picture then. Using Webb’s near-infrared instrument in June 2023, they not only got ...

In June 2023, NASA’s James Webb Space Telescope used its Near-Infrared Spectrograph to capture Neptune’s auroras in stunning detail.

The new Webb observations also reveal why Neptune’s auroras have been invisible until now. Nearly 40 years ago, Voyager 2 recorded a temperature of around 900 degrees Fahrenheit for Neptune’s ...
