NASA’s new space telescope has captured its first starlight and even taken a selfie of its giant, gold mirror.
Over the next few months, the hexagonal mirror segments — each the size of a coffee table — will be aligned and focused as one, allowing science observations to begin by the end of June.NASA's James Webb Space Telescope launched successfully early Christmas morning from French Guiana on South America’s northeastern coast, riding a European Ariane rocket into the sky.

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. This photo provided by NASA shows a"selfie" created using a specialized pupil imaging lens inside of the NIRCam instrument that was designed to take images of the primary mirror segments instead of images of space.
