James Webb First Light

Here is the first ever image processed from the James Webb space telescope’s primary mirror. It shows copies of a distant star HD 84406, individually imaged through Webb’s 18 honey-comb like mirror segments.

This is part of the primary mirror alignment phase. A bit like the process backyard observers go through when we collimate our telescopes.

Over the next several weeks these individual points will converge to form a single image of the star, completing the alignment process and ensuring all components of the 6.5 meter primary mirror are working as one.

You can see the gold plated hexagonal components of the primary mirror in this second picture, which is a selfie the telescope took of its main mirror from outer space.

The astrophysical community awaits Webb’s first active mission pictures which I understand will be images of three of the largest low-albedo asteroids, as well as Jupiter’s red spot and Neptune’s southern polar vortex.
