Astronomers have discovered potentially the most massive black hole ever detected. The cosmic behemoth is close to the theoretical upper limit of what is possible in the universe and is 10,000 times heavier than the black hole at the center of our own Milky Way galaxy.

Astronomers have identified a colossal black hole, potentially the most massive ever detected, at the heart of the Cosmic Horseshoe galaxy located 5 billion light-years from Earth.

Astronomers have used a new method to weigh the ultramassive black hole. They hope this will help them better understand how to find and measure them in the future.

The black hole, spotted 5 billion light-years away in the Cosmic Horseshoe, could be the most massive ever found.

The massive "Cosmic Horseshoe" galaxy system likely hosts a colossal black hole measuring 36 billion times the mass of our sun — one of the largest ever seen in the universe, a new study finds. Scientists found the cosmic monster by peering through a halo of light called an "Einstein ring,

New measurements of the galaxy at the heart of the “Cosmic Horseshoe” indicate that it could house the most massive object ever seen in the universe.

It is 5 billion light-years away, quiet but mind-boggling in size a black hole with 36.3 billion solar masses. Located at the center of the lensing galaxy SDSS J1148+1930, more popularly referred to as the Cosmic Horseshoe,
