Galaxy is the smallest ever discovered at this distance—around 500 million years after the Big Bang. Researchers using the James Webb Space Telescope discovered a tiny galaxy 13 billion years in the past that generated new stars at a high rate for its size. The groundbreaking discovery could help
A University of Minnesota Twin Cities-led team looked more than 13 billion years into the past to discover a unique, minuscule galaxy that could help astronomers learn more about galaxies that were present shortly after the Big Bang.

, and we’ve never looked at galaxies when the universe was this young in this level of detail. The galaxy’s volume is roughly a millionth of theThe James Webb telescope can observe a wide enough field to image an entire galaxy cluster at once. The researchers were able to find and study this new, tiny galaxy because of a phenomenon called gravitational lensing—where mass, such as that in a galaxy or galaxy cluster, bends and magnifies light.
