This is the article submitted by Sorae on September 24, 2022”Neptune as seen by the James Webb Space Telescope]picture. The near infrared camera “NIRCam” was used for photography.
The reason its color is different from the “neptune blue” we usually see is because the Webb Space Telescope mainly observes infrared wavelengths. The human eye cannot see infrared light, so the image is colored red, green, orange and blue according to the four different filters used during its acquisition.
Also, here is a large area annotated image around Neptune. This image shows half of Neptune’s 14 moons.7 satellitesis in the picture. (from top to bottom: Triton, Galatea, Naiad, Thalassa, Despina, Larissa, Proteus)
Neptune’s largest moon is the brightest at the top left.TritonHe is. Triton’s surface is covered in intense nitrogen ice, which reflects on average 70 percent of the sunlight that strikes it. Compared to Neptune, which appears darker because methane strongly absorbs near-infrared light, the Triton in this image isIt looks brighterthat it.

The difference in color between Uranus and Neptune. Why is Neptune bluer?
Uranus and Neptune have a lot in common, including mass, size, and atmosphere composition. However, their appearance (color) is completely different. Seen in visible light, Neptune has a rich dark blue colour, but it’s heavenly…
