NASA’s new space telescope has captured its first starlight and even taken a selfie of its giant, gold mirror.
NASA did not detect the crippling flaw in Hubble's mirror until after its 1990 launch; more than three years passed before spacewalking astronauts were able to correct the telescope's blurry vision.
Webb’s 21-foot , gold-plated mirror is the largest ever launched into space. An infrared camera on the telescope snapped a picture of the mirror as one segment gazed upon the targeted star.NASA released the selfie, along with a mosaic of starlight from each of the mirror segments. The 18 points of starlight resemble bright fireflies flitting against a black night sky.
