James Webb Space Telescope’s latest selfie marks a milestone for the space observatory

New images from the James Webb Space Telescope show the latest big milestone for the space observatory: its 18 mirrors are now aligned enough to act as one massive mirror. The new images released by NASA today include a “selfie” from JWST showing the mirrors’ progress along with updated images of a single star.
Since reaching its final orbit, the telescope’s combined 18 mirrors have been focused on the isolated star HD 84406, which the researchers are using as a target to align the mirrors. Images presented last month showed 18 images of the star that were captured individually on each mirror segment. NASA’s latest image of HD 84406 shows what it looks like when all 18 mirrors work together with the Near-Infrared Camera or NIRCam. They were able to capture not only an image of the star — but also distant galaxies behind the star, too.
