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 detected during Voyager 2’s flyby of the planet, but Webb’s latest discovery is the first direct evidence of the phenomenon.

For the first time, the NASA/ESA/CSA James Webb Space Telescope has captured bright auroral activity on Neptune. Auroras occur when energetic particles,

Neptune's glowing auroras are captured in the best detail yet by NASA's James Webb Space Telescope. Hints of auroras were first faintly detected in ultraviolet light during a flyby of the Voyager 2 spacecraft in 1989.
