Webb telescope snaps clearest picture of Neptune in decades

IT House reported on September 22 that NASA released a photo of Neptune taken by the James Webb telescope, which it claims is the clearest Neptune ring in decades. Let’s take a look. As you can see from the image, the photo shows the dust ring in the near-infrared spectrum. In infrared and visible red light, Neptune does not look as blue as we think it is. Additionally, the photo shows 7 of Neptune's 14 confirmed moons, including the uppermost moon Triton, as well as Galatea, Naiad, Thalassa, Despina, Proteus, and Larissa. Triton looks so bright because it's covered in condensed nitrogen, which reflects 70 percent of sunlight. IT House learned that the distance between Neptune and the sun is 30 times that of the earth and the sun, and the chemical composition of the atmosphere is dominated by hydrogen molecules and helium. This planet is called an ice giant. In the image, the bright spots and streaks on Neptune represent methane ice clouds. Previously, only NASA's Voyager 2 probe flew past Neptune on August 25, 1989, and the Webb telescope took the sharpest picture in decades.
