Image: JWST commissioning - HD 84406 animated segment alignment
Description: Imaging of the star HD 84406 during commissioning of the James Webb Space Telescope, showing the effect of 2rd phase "Segment Alignment", released by NASA on 2022-02-25. After stage 1, the 18 primary mirror segments were only roughly aligned, so far, and not yet focused. So the image showed 18 blurred copies of the same star, in a hexagonal pattern. In phase 2, these were aligned and focused more, as shown by this animation. During the following 3 months, the mirrors will be aligned fully, to focus and synchronize their separate images into one complete image.
