These two images are of the dusty debris disk around AU Mic, a red dwarf star located 32 light-years away in the southern constellation Microscopium. The team used Webb’s Near-Infrared Camera to study AU Mic. NIRCam’s coronagraph, which blocked the intense light of the central star, allowed the team to study the region very close to the star. The location of the star, which is masked out, is marked by a white, graphical representation at the center of each image.

Caused by smash-ups of small, solid objects called planetesimals, these remnants encircle the small star in an enormous debris disk.
The north and east compass arrows show the orientation of the image on the sky. Note that the relationship between north and east on the sky is flipped relative to direction arrows on a map of the ground . Credit: Science: NASA, ESA, CSA, Kellen Lawson , Joshua E. Schlieder , Image Processing: Alyssa Pagan has imaged the inner workings of a dusty disk surrounding a nearby red dwarf star. These observations represent the first time the previously known disk has been imaged at these infrared wavelengths of light. They also provide clues to the composition of the disk.
The team used Webb’s Near-Infrared Camera to study AU Mic. With the help of NIRCam’s coronagraph, which blocks the intense light of the central star, they were able to study the region very close to the star. The NIRCam images allowed the researchers to trace the disk as close to the star as 5 astronomical units – the equivalent of“Our first look at the data far exceeded expectations. It was more detailed than we expected. It was brighter than we expected.
