How astronomers used gravitational lensing, a space-time trick predicted by Einstein, to detect a black hole measuring 30 billion times the mass of the sun.

Black holes, once purely theoretical, are now observable phenomena, offering insights into the universe. Their intense ...

A newly discovered radio halo, 10 billion light-years away, reveals that galaxy clusters in the early universe were already steeped in high-energy particles. The finding hints at ancient black hole ...
