James Webb telescope reveals ancient galaxies with surprising star power.

Using the James Webb Space Telescope, researchers from the University of Minnesota have discovered a unique, tiny galaxy that generated new stars at an extremely high rate for its size. The galaxy is one of the smallest ever discovered at this distance, around 500 million years after the Big Bang, and could help astronomers learn more about galaxies that were present shortly after the universe came into existence. The James Webb telescope can observe a wide enough field to image an entire galaxy cluster at once, and its sensitivity allows scientists to access an entirely new window of data.
