This Is the First-Ever Image of Neptune’s Auroral Glow
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.
