James Webb Space Telescope sends back highest resolution infrared image ever taken from space
The James Webb Space Telescope (JWST) has reached a crucial phase in the alignment of its mirrors. Images from this process have shown that everything is working even better than expected, and the telescope’s operators say that its performance will be able to meet or even exceed the goals that were originally set for it.
JWST peers into the cosmos with the help of 18 gold-plated hexagonal mirrors. For it to work properly, all of these mirrors have to be aligned with extraordinary precision – within nanometres – so that they act as one. When the observatory sent back its first images in February, the mirrors weren’t yet aligned and the images were blurry. Now, although the alignment process isn’t quite complete, the image is crystal clear.
