James Webb Telescope Reveals 12 Billion Years of Evolution of Galaxy Clusters in the Early Universe: Unique Catalog

Stunning discovery: a mature galactic structure, which appeared much earlier than expected by cosmological models, upsets our understanding of the evolution of the Universe. The observation of a spiral barred galaxy, called J0107a, challenges the established theories on the formation of cosmic structures. This colossal entity, whose mass exceeds ten times that of the [...] Article A giant galaxy defies the laws of the primitive Universe appeared…

An international team of astronomers, using the James Webb Space Telescope (JWST), has developed the most detailed map of galaxy systems — gravitationally bound galaxies. The catalog, consisting of 1,678 objects, covers 12 billion years of cosmic evolution and reveals processes previously inaccessible to even the most powerful telescopes. The publication in Astronomy and Astrophysics allows us to understand how galaxies like the Milky Way formed…
