The James Webb Space Telescope continues to fine-tune its mirrors to ultimately peer into the deep and distant universe. The telescope launched Dec. 25 with the 18 hexagonal segments of its primary ...

An image of the star 2MASS J17554042+6551277 taken by the James Webb Space Telescope that confirmed the performance of the spacecraft's optics. The rays are diffraction patterns from the shape of the ...

With the exciting process of deployment complete, the James Webb Space Telescope team is now embarking on their next challenge: Aligning the telescope’s mirror segments. This slow, months-long process ...

A mosaic of images taken by the James Webb Space Telescope, showing the images of a single star as seen by the 18 segments of the spacecraft's primary mirror as part of the mirror alignment process.

While the purpose of this image was to focus on the bright star at the center for alignment evaluation, Webb’s optics and NIRCam are so sensitive that the galaxies and stars seen in the background ...

With the James Webb Space Telescope at its final destination in orbit around the sun, now the telescope has to go through a series of alignment processes to get it ready for collecting science data.

Just weeks after the excitement of launch, the James Webb Space Telescope is already seeking focus in space. Engineers are beginning alignment procedures for the recently unfolded 18-segment massive ...
