"JWST Unveils Distant Galactic Merger and First Light Flood"

Using the Webb telescope, astronomers have discovered a massive galactic merger, Gz9p3, occurring about half a million years after the Big Bang, making it one of the earliest and most distant mergers ever observed. This finding challenges previous understanding of how quickly galaxies formed in the early Universe and suggests that stars in those galaxies evolved faster than expected. The merger, still in progress, has provided insights into the formation of new stars and the dynamics of galactic mergers in the early Universe, prompting astronomers to reevaluate their models of star birth and galaxy formation.
