See a 3D map of a distant colossal cluster of galaxy clusters
Astronomers have created a 3D map of a distant supercluster of galaxies, COSMOS-Z3.1-A, revealing that it is a massive structure rather than a simple cluster. The study utilized data from the ODIN project to clarify the depth and scale of these early universe structures.
Why it matters
Mapping these colossal structures helps scientists better understand the formation and evolution of the universe during its early stages.
Astronomers have taken a patch of distant sky and turned it into a 3D map, revealing a colossal system with about 5,000 times more mass than the Milky Way in the early universe.In previous space pictures, this area looked like a flat painted ceiling. Galaxies appeared close together simply because they lined up from our point of view, even if some were separated by billions of light‑years in depth.Because of that optical illusion, astronomers couldn't say for sure whether they were looking at one gigantic galaxy cluster under construction or a corridor where many clusters were in development. The 3D map answered that. By measuring how far away the galaxies are, scientists watched that view transform into a chain of clumps. That new way of looking at the data showed this was not a construction zone for a regular galaxy cluster but a supercluster - a cluster of clusters.
