The James Webb Space Telescope has delivered unprecedented images of the planet Neptune and its rings, which provide valuable information about its atmosphere, NASA announced on Wednesday, September 21. Astronomers had not had such a clear view of the most distant planet in the solar system since the brief and unique passage of a probe , Voyager 2, in the vicinity of this icy giant in 1989. The telescope’s infrared vision provides a new way to analyze its atmosphere, said Mark McCaughrean, adviser for science and exploration at the Ag European Space Agency (ESA). 🪐We’re always big fans of Saturn, but Neptune’s rings are giving us all the feels in this new @NASAWebb image. It’s… — NASA Solar System (@NASASolarSystem) View Tweet The telescope removes all glare from the sun’s reflection off Neptune’s surface and light pollution from its surroundings, so “To begin to guess the atmospheric composition” of the planet, told AFP this astronomer who worked for more than 20 years on the James Webb project. Neptune had a bluish appearance in images taken in the visible waveband by the Hubble telescope, due to the presence of methane in its atmosphere. Neptune in a new light! 🔵 Hubble’s view of this planet looks pretty different from @NASAWebb’s new image, on the r… — Hubble (@NASAHubble) View tweet Featuring James Webb’s NIRCam instrument, which works in the near infrared, the planet takes on a colorized hue in a greyish white. The image also shows “strange light” at one of Neptune’s poles, NASA said in a statement. The telescope also captured images of seven of the planet’s fourteen known moons. And in particular of Triton, which resembles by its brilliance a small star. Larger than the dwarf planet Pluto, it also appears brighter than Neptune because of the reflection of sunlight off its icy surface. That’s no star. It’s Neptune’s large, unusual moon, Triton! Because Triton is covered in frozen, condensed nitrogen… — NASA Webb Telescope (@NASAWebb) View tweet Astronomers looking for planets outside our solar system have found that those like Neptune or Uranus are the most common. “The ability to observe these closely will facilitate the observation of others (icy giants) orbiting other stars” than our Sun, explained Mark McCaughrean. In service since last July, the James Webb is the most powerful space telescope ever deployed. It will enable a kind of astronomy “that was unthinkable even five years ago”, said Mark McCaughrean.
