Post alignment of the telescope, Webb has taken its second "selfie", using a specialized lens in the NIRCam to photograph the primary mirror, allowing engineers confirm mirror positioning. Now that all 18 mirror segments reached alignment, every mirror is illuminated since they are all collecting light from the same star, in concert. Compare with Webb's first (pre-alignment) "selfie".
