This is the first photograph of the James Webb Space Telescope.

Just recently, US President Joe Biden presented First untested full color photo of the James Webb Space Telescope.
This image, which took less than a day to obtain, shows the galaxy cluster SMACS 0723, now called Webb’s First Deep Field. This is the deepest and sharpest infrared photo of the early universe.

Thousands of galaxies, including some of the faintest objects ever seen in the infrared, came into the telescope’s field of view for the first time. This piece of the vast universe covers an area of ​​the sky about the size of a grain of sand, which a person on earth holds at arm’s length.

The curvature in the center of the image is not a problem with the telescope’s optics, nor is it a defect. This is a gravitational lensing phenomenon, caused in this case by the presence of another cluster of galaxies in the foreground (it is not visible in the image), the gravitational field of which distorts the light from SMACS 0723 and visually brings this cluster closer. In fact, this is a natural telescope of a cosmic scale.
