IC 1101 holds the title of the largest galaxy known to humanity, and its colossal size is almost beyond comprehension. Located approximately 1.045 billion light-years away from Earth, this galaxy is not just big,

Scientists have detected the collision of two massive black holes merging beyond the Milky Way. The two black holes, each with a mass more than 100 times that of the sun, had been circling each other for a while before finally colliding to form an even bigger black hole about 10 billion light years from Earth.
