James Webb telescope discovers stellar clumps in distant galaxies

Astronomers have obtained an image of stellar clumps thanks to the James Webb telescope. It is reported by the Stockholm University.

This was done using gravitational lensing, which is caused by closer galaxies. “These clusters of galaxies are so massive that they bend the light rays passing through their center, just as Einstein predicted in 1915. And this, in turn, creates the effect of a magnifying glass: images of background galaxies are enlarged, ”explains Adelaide Claissens, one of the authors of the work.

As a result, the authors managed to detect stellar clumps in galaxies at a distance of more than 8 billion light years. They formed when the universe was young and its age ranged from one to five billion years. “Images from the James Webb telescope show that we can now detect very small structures inside very distant galaxies and that we can see these clusters in many of these galaxies,” explains the scientist. In particular, images of the galactic cluster SMACS0723 were obtained.

This will allow scientists to determine the influence of stellar clumps on the evolution of galaxies.

Previously, biologists repaired damage in the brain of a rat with a “patch” of human neurons.
