Is there a black hole larger than TON 618? TON 618 is estimated to have a mass of 66 billion times that of our sun. The black hole in Holm 15A is estimated to have a mass of 40 billion times...
How far away is the black hole in M87? M87 lies about 55 million light-years from Earth. Is M87 bigger than Milky Way? M87 is one of the most massive galaxies in the local Universe. Its diameter is estimated at 132,000...
How large is the mass of Messier 87? Is M87 bigger than Sgr A? The two images look similar, despite the differences between the two black holes: at four million times the mass of the Sun, Sgr A* is a thousand...
How far away is the black hole in galaxy M87? M87*, which lies 55 million light-years away, is one of the largest black holes known. While Sgr A*, 27 000 light-years away, has a mass roughly four million times the Sun’s...
Why is the black hole called M87? It’s also apropos because two of the eight powerful telescopes used to generate the first black hole image are located in Hawaii — so seems fitting that the M87 black hole’s name be tied...

How much bigger is M87 black hole than ours? The breakthrough follows the EHT collaboration’s 2019 release of the first image of a black hole, called M87*, at the centre of the more distant Messier 87 galaxy. The two black holes...
What is the black hole in M87 called? During five nights in April 2017, the EHT collaboration used eight observatories across the world to collect data from both the Milky Way’s black hole — called Sagittarius A*, after the constellation in...
Does the Milky Way have 2 black holes? The Event Horizon Telescope (EHT) has now produced images of two supermassive black holes: the one in the center of a galaxy called M87 and the one at the center of our own...
