In December of 2019, astronomers announced the discovery of one of the most perfect macroscopic objects, the largest hard-disk in the cosmos –the biggest black hole ever measured in the nearby universe at the center of an elliptical galaxy in galaxy cluster Abel 85 that’s 40 billion times the sun’s mass, or roughly the size of our solar system, harboring two-thirds the mass of the 100-billion stars in the Milky Way.

The galaxy is Holm 15A, a huge elliptical galaxy at the center of a cluster of galaxies called Abell 85, which consists of more than 500 individual galaxies, at a distance of 700 million lightyears from Earth, twice the distance for previous direct black hole mass measurements.

“But we already had some idea of the size of the black hole in this particular galaxy, so we tried it.” The team captured a snapshot of Holm 15A’s stars in orbit around the galaxy’s central black hole and created a model to help them calculate the black hole’s mass.

Their central black holes combine as well and make larger black holes, galactic monsters which kick huge swaths of nearby stars out to the edges of the newly formed galaxy leaving its faint center barren, or “cored.”.

This series of mergers also created the black hole in its center, a monster about as big as our solar system but with the mass of 40 billion suns

“A Galaxy Fell Through It” –Creating the EHT’s Monster M87 Black Hole

.“A medium-sized galaxy fell through the center of M87, and as a consequence of the enormous gravitational tidal forces, its stars are now scattered over a region that is 100 times larger than the original galaxy!” said Ortwin Gerhard, head of the dynamics group at the Max Planck Institute for Extraterrestrial Physics about the monster elliptical galaxy that harbors the now iconic black hole the size of our solar system imaged for the first time ever by the Event Horizon Telescope (EHT) on April 10, 2019
