Astronomers have identified an ultramassive black hole that could be the largest ever measured, hidden in a distant galaxy known as the Cosmic Horseshoe. This gargantuan object, weighing about 36 billion Suns, warps space so strongly that light from a background galaxy is bent into a perfect Einstein ring.

The newly discovered black hole lies in one of the largest galaxies ever observed, known as the Cosmic Horseshoe. This galaxy is so massive that it bends spacetime, causing light from a more distant galaxy to curve around it and form a glowing horseshoe-shaped arc called an Einstein ring.

The discovery sets a new benchmark for how early supermassive black holes can form and raises questions about their origin and growth. "When looking for black holes, this is about as far back as you can practically go,
