‘Absolutely phenomenal’: Webb Telescope’s first images have scientists giddy
The James Webb Space Telescope (JWST) has passed its first assignment with flying colours, after it handed in a spectacular photo to NASA.
On Wednesday, officials at the space agency shared a stunning photo of a star captured by the telescope during its alignment process, in which several in-focus galaxies and distant stars can be seen in the background.
The Webb’s primary mirror is made up of an array of 18 individual mirrors that, once properly aligned, will act as a single mirror.

And I’m happy to say that the optical performance of the telescope is absolutely phenomenal, it is really working extremely well.
