Scientists discovered an extremely hot and old galaxy cluster from just 1.4 billion years after the Big Bang, which challenges current cosmological theories. The cluster's unexpected heat is likely due to energy from supermassive black holes at its core, suggesting galaxy clusters evolve more explosively than previously thought, potentially reshaping our understanding of the early universe.

Astronomers have confirmed the first known system where three galaxies, each hosting active supermassive black holes, are merging, providing new insights into galaxy and black hole evolution through high-resolution radio imaging. The system, located 1.2 billion light-years away, shows all three black holes actively feeding and launching jets, a rare and significant discovery that advances our understanding of cosmic growth processes.

An international team of astronomers has found evidence suggesting that the relationship between ultraviolet and X-ray emissions in quasars has evolved over billions of years, challenging the long-standing assumption of its universality and potentially impacting cosmological models. Using data from eROSITA and XMM-Newton, they observed differences in this relationship in quasars from the early universe compared to the present day, which could influence our understanding of black hole growth and the universe's expansion.
