Astronomers have discovered an ultramassive black hole estimated to be the same mass as 32.7 billion Suns.
Published Apr 2nd, 2023 9:24PM EDT2.7 billion light years away, in a galaxy cluster known as Abell 1201, an ultramassive black hole lurks, measuring upwards of 32.7 billion times the mass of our Sun. This new measurement exceeds astronomers’ previous estimates by at least 7 billion solar masses. It’s one of the biggest black holes astronomers have ever detected and cuts close to how large we believe they can be.
These black holes are much bigger than supermassive black holes like those found at the center of galaxies. And, because they’re so massive – and contain so much mass – they should theoretically be easier to find. However, as I noted above, it all depends on how active the black hole is and how much heat it emits. That’s because, by default, ultramassive black holes don’t emit light.
However, it wasn’t until 2017, when astronomers discovered a second smear, that they began to look more in-depth at the discovery. More recently,
