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.

NASA's James Webb Space Telescope has captured a detailed image of Neptune's auroras, making it the first observatory to do so. Though Voyager 2 was the first spacecraft to fly by Neptune, detect its auroras in infrared, and snap a picture of the majestic ice giant, Webb's image offers direct, visible evidence of Neptune's vibrant light displays.

NASA's James Webb Space Telescope (JWST) has snapped a spectacular image of a "cosmic tornado" being burped out from a baby star. The image reveals an outflow of hot gas from a newborn star — known as a Herbig-Haro object — situated about 625 light-years from Earth in the constellation Chamaeleon.
