Scientists suspected the ice giant hosted auroras—and had already observed them on Jupiter, Saturn and Uranus. But an observation of Neptune's lights remained elusive for decades

Neptune's elusive auroras have been finally revealed thanks to the James Webb Space Telescope. Astronomers scouring through the combined data from Webb and the Hubble telescope have discovered the presence of trihydrogen cation (H3+), which is created in auroras .

In a major breakthrough, the James Webb space telescope of NASA has for the first time captured auroral activity on Neptune, a task that has kept the scientists busy for a long time, despite successful detections on other planets in the solar system,
