Seeing the galaxies peppering this image, I can't wait for James Webb's version of the 'dark sky' Hubble image. It would be even better if the same patch of sky was used, just with the increased vision of Webb's imaging.

Can somebody explain why there are 6 lines coming from the center of the star? Is this an artifact of the hexagonal submirrors? I had the impression that these would form a "perfect" mirror with the alignment finely tuned. Was I mistaken?
