The James Webb Space Telescope has just served up a couple more sublime images, this time showing the Ring Nebula in astonishing detail.
First spotted in the 18th Century and located around 2,500 light-years from Earth, the Ring Nebula’s colorful main ring is made up of gas thrown off by a dying star at the center of the nebula.
Webb captured the images using two different cameras. The first one was taken by its near-infrared camera and shows the intricate details of the filament structure of the inner ring. The Ring Nebula, which ESA describes as being shaped like a “distorted donut,” contains around 20,000 dense globules that are rich in molecular hydrogen. In contrast, the inner region is an area of very hot gas.
ESA notes that while the middle of the donut may appear to be empty, in reality it’s full of lower density material that stretches both towards and away from us, “creating a shape similar to a rugby ball slotted into the donut’s central gap.”

Webb reveals intricate details in the remains of a dying starNASA's James Webb Space Telescope obtained images of the Ring Nebula, one of the best-known examples of a planetary nebula. Much like the Southern Ring Nebula, one of Webb's first images, the Ring Nebula displays intricate structures of the final stages of a dying star. Roger Wesson from Cardiff University tells us more about this phase of a sun-like star's stellar lifecycle and how Webb observations have given him and his colleagues valuable insights into the formation and evolution of these objects, hinting at a key role for binary companions.
