The first photo of a star taken by the (almost) perfectly adjusted James Webb space telescope has arrived.

In February, NASA released the first image ever taken by the most expensive and complex space telescope ever, the James Webb. The image at the time was of the star HD 84406, located about 260 light years from Earth in the constellation of Big Dipper, not far from the Göckelsberg star. As the instruments had not been fine-tuned at the time, the image was slightly blurred found success, and eighteen points of light could be seen in the image (a total of eighteen of them are part of the telescope).

After much preparation, the mirrors have now finally been fine-tuned with the NIRCam imaging tool, so that the instrument can take its first image with its (almost) perfectly adjusted instruments. The unusual image is of the star 2MASS J17554042+6551277, located 2000 light years away illustrated by, whose light is a hundred times dimmer than the human eye can detect.

The incredibly complex James Webb space telescope reached its destination, the second Lagrange point, about 1.5 million kilometres from Earth, on 24 January. The space telescope will gather information about the earliest ages of the universe: it will study the cosmos, the planets and moons of the Solar System, and the oldest and most distant galaxies, in the infrared region, which is largely absorbed by our planet's atmosphere.
