Astronomers have discovered an ultra-massive black hole hiding in plain sight at the very heart of the Cosmic Horseshoe galaxy, five billion light-years from Earth (New Scientist, August 7, 2025).

This heavenly leviathan bends light itself, warping space and time with its incredible gravitational pull.
