JWST discovers highly evolved galaxy cluster at cosmic noon, challenging theories of early universe structure formation
By
Robert Lea
Summary
Astronomers using the James Webb Space Telescope have observed XLSSC 122, a massive and densely packed galaxy cluster at 'cosmic noon' — a period roughly 2-3 billion years after the Big Bang. The cluster, first detected in 2014, appears far more evolved than expected for its early epoch, potentially challenging existing theories of cosmic structure formation and evolution. The findings suggest that galaxy clusters may have formed and matured much earlier than previously thought possible.
