NASA unveils first images from James Webb Space Telescope

The image represents the early stages of the telescope 18 main mirror segments properly aligning before JWST reaches its full potential.

The image is blurry, but this is actually a good starting point in the long process of adjusting JWST mirrors to take ultra-sharp photos of the distant Universe.

The 18 points of light that appear in the image all represent the same isolated star, known as HD 84406, seen by a different primary mirror segment.

Light collected from each primary mirror segment was reflected back to Webb’s secondary mirror, then measured using one of the telescope’s key imaging instruments, the Near Infrared Camera, or NIRCam.

according to NASA. The 18 images of HD 84406 were pieced together from more than 1,500 images collected as Webb was pointed to various positions around the expected location of the star.

The Mirror Will Begin To Align Correctly Following The Various Adjustments That The Telescope Will Make Over The Coming Months. 

On January 4th, JWST successfully deployed its giant sunshield, which is essential to keeping its instruments cold.
