NASA's James Webb Space Telescope captured a stunning image of a brain-shaped nebula around a dying star. The image shows new details about the structure and development of this unusual cloud of gas and dust.

The James Webb Space Telescope has provided a clearer look at a mysterious nebula surrounding a dying star. This nebula, called PMR 1, has a striking brain-like shape, which is why it's been nicknamed the 'Exposed Cranium' nebula.

The telescope observed the nebula using both near-infrared and mid-infrared light, revealing features that were not previously visible. The image shows clear signs of different stages in its development - an outer shell of gas that was expelled earlier and a more complex inner region that contains a mix of gases and detailed structures.

The layers reflect how the star has shed material over time. Images from Webb's NIRCam and MIRI instruments both highlight a dark lane running vertically through the center of the nebula, which splits the cloud into two sections resembling the left and right sides of a brain.

Webb's high-resolution images suggest that this dark lane may be connected to an outburst or flow of material from the central star. Evidence of this activity is especially visible near the top of the nebula in the MIRI image, where gas from the inner region appears to be pushed outward.

The star is nearing the end of its fuel-burning 'life' and will eventually shed its outer layers into space. The James Webb Space Telescope has captured a snapshot of this process as it unfolds.
