30 Years On: New Webb Image Captures Clearest View of Neptuneโ€™s Rings in Decades

NASAโ€™s James Webb Space Telescope shows off its capabilities closer to home with its first image of Neptune. Not only has Webb captured the clearest view of this distant planetโ€™s rings in more than 30 years, but its cameras reveal the ice giant in a whole new light.

Most striking in Webbโ€™s new image is the crisp view of the planetโ€™s rings โ€“ some of which have not been detected since NASAโ€™s Voyager 2 became the first spacecraft to observe Neptune during its flyby in 1989. In addition to several bright, narrow rings, the Webb image clearly shows Neptuneโ€™s fainter dust bands.What do we see in Webb’s latest image of the ice giant Neptune? Webb captured seven of Neptuneโ€™s 14 known moons: Galatea, Naiad, Thalassa, Despina, Proteus, Larissa, and Triton. Neptuneโ€™s large and unusual moon, Triton, dominates this Webb portrait of Neptune as a very bright point of light sporting the signature diffraction spikes seen in many of Webbโ€™s images.
