Using the James Webb Space Telescope, an international team of scientists has uncovered a remarkable system of five galaxies that are merging at an early stage in the universe's history, approximately 800 million years following the Big Bang. This significant finding, published in the journal 'Nature Astronomy', reveals an unexpected level of cosmic complexity, indicating that large and dynamic structures formed more rapidly than previously believed.

The discovery demonstrates a surprising number of interacting galaxies in this early epoch, contradicting previous assumptions that most galaxies were smaller, simpler, and isolated during this period. The newly identified system comprises five compact, star-rich galaxies positioned remarkably close to each other, at distances estimated to be only tens of thousands of light-years apart, making them much nearer compared to most neighboring galaxies in today's universe.

Dr. Weida Ho from Texas A&M University noted that this discovery is particularly exceptional as the merger of such a large number of galaxies at this early stage of the universe was unforeseen. This challenges traditional models of galaxy formation and suggests a reconsideration of the timeline and mechanisms responsible for cosmic evolution.
