Scientists have a good idea how stars should form in the central galaxies of rich clusters. The hot gas surrounding a cluster’s dominant innermost galaxy cools rapidly, sparking furious star formation. The problem: No one had found evidence for this cooling gas, and most central galaxies don’t create many stars. Astronomers suspect the solution toContinue reading “JWST’s view of the Phoenix Cluster sparks scientific conundrum”
