James Webb Space Telescope Discoveries Astrophysics Early Universe Evolution

Astronomers using the James Webb Space Telescope have identified two early-universe galaxies, COLA1 and NEPLA4, featuring supermassive black holes that are disproportionately large compared to their host galaxies. The researchers suggest these objects may represent a 'missing link' in the evolution of quasars and galaxy formation in the early universe.
