The James Webb Space Telescope, a joint effort between NASA, ESA, and CSA, has captured stunning images of the Ring Nebula, also known as M57 and NGC 6720. Located 2,500 light-years away from Earth, this well-known planetary nebula has been observed with unprecedented detail. The new images taken by the Webb telescope provide remarkable spatial resolution and spectral sensitivity, revealing unique details in both infrared observations.
The images show intricate details of the filament structure of the inner ring and specific details in the concentric features of the outer regions of the nebula. One interesting finding is the presence of around 20,000 dense globules rich in molecular hydrogen within the nebula, while the inner region shows very hot gas. The main shell of the nebula contains a thin ring of carbon-based molecules known as polycyclic aromatic hydrocarbons (PAHs), and there are approximately ten concentric arcs located just beyond the outer edge of the main ring.
Studying nebulae like the Ring Nebula allows astronomers to learn about the star that created it. The unique shape of the Ring Nebula resembles a distorted doughnut, with a brightly colored barrel of material extending away from us. The center of this
