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

At 36 billion solar masses, the newly discovered black hole is so massive that it seems to break some theories of the ...

Astronomers have measured the weight of a huge black hole — 36 billion times the mass of our sun, or six times the size of our entire solar system — in an old and dead galaxy near Earth. This cosmic ...

The astronomers estimated that the "ultramassive" black hole is over 10,000 times the mass of the Milky Way's black hole.
