This composite image provided by NASA on Wednesday, Sept. 21, 2022, shows three side-by-side images of Neptune. From left, a photo of Neptune taken by Voyager 2 in 1989, Hubble in 2021, and Webb in 2022. In visible light, Neptune appears blue due to small amounts of methane gas in its atmosphere. Webb’s Near-Infrared Camera instead observed Neptune at near-infrared wavelengths, where Neptune resembles a pearl with thin, concentric oval rings. (NASA, ESA, CSA, STScI via AP)
