Feb. 25, 2022 1:04 p.m. PT 6park.comEnlarge Image The "image stacking" phase of the Webb telescope alignment involves the creation of a single unified image out of multiple images. This is 18 segments stacked to show a single star.
NASA/STScIWhen we saw one of the James Webb Space Telescope's first images earlier this month, it was made up of 18 versions of the same star coming from 18 different mirrors. On Friday, NASA shared a view of that star again, but this time as a single, shining object.
It's one thing to build and launch a big, complex, next-gen space telescope. It's another to shepherd it through a complicated deployment so it can take a proper look at the universe. Webb is in the middle of a multi-phase mirror alignment and it's going swimmingly so far. The goal is to get all of Webb's many mirrors working together as one.
