In a study published on Wednesday in the journal Nature Astronomy, scientists say unique auroras are visible on either side of Neptune’s equator. This discovery will allow scientists to study aspects of Neptune that have previously been out of reach.

Webb has filled in many gaps left by Voyager 2, the only spacecraft to visit the planet. In 2022, the telescope captured Neptune's ghostly rings and revealed a band of clouds around a known vortex at the planet's south pole for the first time.

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