NASA missions spot cosmic ‘Wreath’ displaying stellar circle of life

Cosmic Wreaths and Christmas tree clusters

A new image of NGC 602 combines data from NASA’s Chandra X-ray Observatory and the James Webb Space Telescope. The image shows a dark, ring-like shape around the cluster, made of dense dust clouds in orange, yellow, green, and blue, as seen by the Webb telescope.

Red splashes, representing X-rays, add shading and highlight the different layers within the wreath-like cloud.
