Hubble Space Telescope image showing the Great Dark Spot has disappeared. Closer view of the Great Dark Spot and the 'scooter'. The Webb telescope found both prominent rings as well as bands of dust. Color image of Neptune showing its 'Great Dark Spot'. It is difficult to observe these rings from afar because they are close to the planet and obscured by Neptune's brightness. Neptunes elliptical, oval-shaped orbit keeps the planet an average distance from the sun of almost 2.8 billion miles (4.5 billion kilometers), or roughly 30 times as far away as Earth, making it. These appear as brilliant, bright features, NASA says.Īlso prominent in the new image are Neptune's rings, which have not been directly observed since Voyager 2 flew by the planet in 1989. In the new view of Neptune, the exception to this is the planet's high-altitude methane ice clouds, which reflect sunlight before it can be absorbed by the methane. This is because the methane in Neptune's atmosphere absorbs reddish and infrared light. The Webb telescope, however, observes light in the infrared portion of the spectrum, so its "Near-Infrared Camera" photos show a ghostly white planet. The third-largest planet in our Solar System, Neptune often appears bright blue in images due to the presence of gaseous methane. The James Webb Space Telescope's first images of Neptune, the mysterious ice giant that orbits in the far reaches of the outer solar system, were so. NASA released the first images of this world on Wednesday. Recently, astronomers took data on the eighth planet from the Sun in our Solar System, Neptune. Scientists are wasting no time in pointing the powerful new James Webb Space Telescope all over the Universe, as well as into our own backyard. NASA, ESA, CSA, STScI reader comments 157 with
