Young Galaxy Cluster Surprises Scientists with Heat Comparable to Solar Surface
Unexpected Heat in a Very Young Galaxy Cluster In a surprising turn for cosmology, researchers have identified a galaxy cluster that is both remarkably young and exceptionally hot—hotter, in fact, than the surface of the Sun. This challenges longstanding ideas that young clusters should be cooler as they form from the gradual assembly of surrounding…

Hot Young Galaxy Clusters Challenge Formation Theories
Unpacking a surprising finding in the cosmos For decades, astrophysicists have offered a fairly consistent picture of how galaxy clusters form. Theories suggested that younger clusters—those that assemble earlier in the universe’s history—should be relatively cooler, having not yet accumulated the most energetic material that heats intergalactic gas. Recent observations, however, tell a different story.…

A Very Young Galaxy Cluster Goes Heating Against the Theory: New Findings Shock Researchers
Unexpected Heat in a Very Young Galaxy Cluster New research is turning a widely accepted assumption about galaxy clusters on its head. Prevailing theories suggested that young galaxy clusters should be relatively cool as they assemble and carve out their gravitational wells. But a recently observed, very young cluster has emerged as a striking exception,…
