Webb telescope detects massive stars in the universe.

The James Webb Space Telescope has detected the first chemical signs of supermassive stars, which are "celestial monsters" that blaze with the brightness of millions of Suns in the early universe. The largest stars observed so far have a mass of around 300 times that of our Sun, but the supermassive star described in a new study has an estimated mass of 5,000 to 10,000 Suns. The researchers theorize that these huge stars are born from successive collisions in the tightly packed globular clusters, and they shoot out chemical "pollution" that feeds young forming stars, giving them a greater variety of chemicals.
