AI Summary

Astronomers have made an unexpected discovery using NASA's Hubble Space Telescope. The telescope has detected ultraviolet light emanating from a galaxy that existed approximately 1.4 billion years after the Big Bang. This galaxy is notable for containing tightly clustered young stars. These stars are capable of producing ionizing light, which can alter the surrounding environment. The light can clear out the opaque, neutral gas within and around the galaxy. The detection of this ultraviolet light suggests that the galaxy is actively transforming its neighborhood.
