James Webb’s first star portrait is the result of NASA images through the space telescope. While it doesn’t reveal any hidden secrets in the universe’s past, the data is important for the future.
Calibration shots taken from the same star are to ensure the main mirror and the Observatory’s instruments are aligned correctly. This photo is an early indicator that the telescope is functioning as expected and is ready to begin its next mission.

Stunning!The Portrait of James Webb’s First Star Is More Than It Seems
From a Webb Telescope blog post, there is the first NASA image taken by NIRCam. Every visible dot is the same star. There is a mosaic that incorporates 18 primary mirror images.
HD 84406 as a bright and isolated star in the constellation Ursa Major. Each is displayed as a display of each of the 18 different mirror segments in the James Webb master mirror.
Focus is reflected into the NIRCam sensor. In other words, James Webb captured the initial available data to ensure that the mirror segments were aligned correctly before any further scientific missions.

Actually capturing every image is not as easy as one might think. Pointing the telescope at HD 844406 and snapping the shutter up to 18 times certainly requires precision.
NASA said that the process of capturing the image involved the appointment of the James Webb Telescope. With 156 different positions around the predicted star location. James Webb had captured 1560 images as it happened and began to translate them into 54 GB of raw data.
The first available star portrait of James Webb through the zoom process helped NASA scientists align each mirror segment correctly and precisely.
Webb’s optical telescope element manager, Lee Feinberg revealed that this extraordinary telescope has not only spread its wings but is now an eye-opener. The mosaic shows 18 points of starlight arranged randomly.

The image is just the beginning so it takes about a month to complete the alignment steps and process.
What appears to be a simple image of blurry starlight today forms the basis for aligning and focusing the telescope. The goal is that the web is able to provide an unprecedented view of the universe.
Over the next month or so, the NASA team gradually adjusted the mirror segments to 18 images into a single star. NASA scientists love to see images from James Webb.
This is a confirmation that the mirror has successfully reflected light onto the NIRCam. A view of the special pupillary imaging lens inside the NIRCam instrument. The design is to take pictures of the main mirror segment to space. James Webb’s first star portrait brings one step closer to the start of a scientific mission. (R10/HR-Online)
