JWST has captured a pair of beautiful images showing the Ring Nebula, a dying star in the midst of a final flurry at the end of its stellar lifecycle.
Also known as M57 and NGC 6720, the Ring Nebula is typical of a planetary nebula, an ejection of ionized gas emitted from red giant stars late in their lives.
What you’re seeing is essentially a fizzing outpour of gas being thrown out of a star at the center of the nebula. Once this drama is over, it will complete its transition to become a white dwarf, a small but super-dense body that’s the final evolutionary stage for a star like the Sun.
The latest pair of images were shot by two instruments onboard JWST: NIRCam (Near-InfraRed Camera) captures the fine details of the filament structure of the inner ring, while MIRI (Mid-InfraRed Instrument) reveals the features in the outer regions of the nebulae’s ring.
This image of the Ring Nebula appears as a distorted doughnut. The nebula’s inner cavity hosts shades of blue and green, while the detailed ring transitions through shades of orange in the inner regions and pink in the outer region. The ring’s inner region has distinct filament elements.

“The nebula is shaped like a distorted doughnut. We are gazing almost directly down one of the poles of this structure, with a brightly colored barrel of material stretching away from us. Although the center of this doughnut may look empty, it is actually full of lower density material that stretches both towards and away from us, creating a shape similar to a rugby ball slotted into the doughnut’s central gap,” the European Space Agency said in a statement.
