Astronomers got an image of the star clusters thanks to the James Webb telescope. Reported by Stockholm University.
This was done using gravitational lensing caused by closer galaxies. “These galaxy clusters are so large that they bend light rays passing through their centers, just as Einstein predicted in 1915. And this creates a magnifying effect: images of background galaxies are magnified,” explains Adelaide Claissens, one of the study’s authors.
As a result, the authors were able to detect star clusters in galaxies at a distance of more than 8 billion light-years. They formed when the universe was young and ranged in age 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 see these clusters in many of these galaxies,” explains the scientist. In particular, images of the SMACS0723 galactic cluster were obtained.
This will allow scientists to determine the influence of star clusters on the evolution of galaxies.
