🪐 We’re always big fans of Saturn, but Neptune’s rings are giving us all the feels in this new @NASAWebb image. It’s the clearest view of the rings in more than 30 years. Neptune’s rings were last clearly imaged by NASA's Voyager 2 in 1989, seen in the second image. Voyager had been traveling for 12 years before reaching this distant planet that’s more than 2.8 billion miles from the Sun. Image 1: A pearly Neptune is in the center of the image on a black background. Neptune’s rings are a standout feature. Surrounding Neptune and its rings are 6 other moons, seen as tiny dots. Clockwise, starting from 3 o’clock, they are: Despina, Proteus, Larissa, Thalassa, Naiad, Galatea. Image 2: Five rings appear over two images bisected vertically by a black bar. Three of the rings are sharp and fine and two are hazy and more diffuse. The two 591-second exposures of the rings of Neptune were taken with the clear filter by the Voyager 2 wide-angle camera on Aug. 26, 1989 from a distance of 280,000 kilometers (175,000 miles). The two main rings are clearly visible and appear complete over the region imaged. These long exposure images were taken while the rings were back-lighted by the sun at a phase angle of 135 degrees. This viewing geometry enhances the visibility of dust and allows fainter, dusty parts of the ring to be seen. The bright glare in the center is due to over-exposure of the crescent of Neptune.
