Initial imaging of star [[HD 84406]] by James Webb Space Telescope, at completion of first phase of initial alignment, released by NASA on 2022-02-18, annotated to show related primary mirror segments.

Summary[edit]

Description
English:
English: Initial imaging of the star HD 84406 by James Webb Space Telescope, at completion of first phase of initial alignment, released by NASA on 2022-02-18.

The 18 primary mirror segments are only roughly aligned, so far, and not yet focused. So the image shows 18 blurred copies of the same star, in a hexagonal pattern. During the following 3 months, the mirrors will be aligned fully, to focus and synchronize their separate images into one complete image.

The inset image shows the primary mirror segments and their official reference ID's, and the image is annotated to show which segment was responsible for which of the copies of the star.
