Neptune Through the Years

Here are three side-by-side images of Neptune. From left to right, the first is labeled as taken by Voyager 2 in 1989. It’s a dark blue sphere with some pale blue or white streaks against a black background. The second is labeled as taken by Hubble in 2021. It’s a fuzzier and paler blue sphere also set against a black background. The third is labeled as taken by Webb in 2022. As seen in infrared light, Neptune resembles a pearl with thin, concentric oval rings.

In visible light, Neptune appears blue due to small amounts of methane gas in its atmosphere. Webb’s NIRCam instrument instead observed Neptune at near-infrared wavelengths, so Neptune doesn’t look so blue!
