Here's what keeps the Milky Way's huge black hole at bay

Overwhelming Power Compared to other supermassive black holes scattered throughout the universe, the core of our galaxy mysteriously rests. And now NASA thinks it knows why. A strong magnetic field in the center of the Milky Way is precisely aligned to protect the black hole of our galaxy, Sagittarius A *, from spewing or spitting high-energy radiation into the cosmos, …

Astronomers measure tiny black hole in the nearby dwarf galaxy

When people think of a black hole, they typically imagine a large, burning cosmic being, millions or billions of times larger than our sun. However, not all black holes are supermassive, and the smaller ones are also important. A team of scientists from the University of Michigan measured the mass of a small black hole in a nearby dwarf galaxy …

Scientists Solve Cosmic Mystery Through Black Hole Simulations

The mystery Over time, black holes pool matter that orbits – and eventually consumed by – the hole. These whirlpools of doomed matter are known as accretion disks. Nearly everything known about black holes has been discovered from study disks, which – unlike the holes themselves – are bright and clearly visible. Accretion disks, so how to control a black …

Haunting black hole mystery

The accretion disk (red) aligns with the equatorial plane of the black hole. Sasha Tchekhovskoy / Northwestern University / Matthew Liska / University of Amsterdam                                                  Using a supercomputer and some custom-built code on an international team of researchers has created the "most detailed" simulation of a black hole proving a long-standing theory that has puzzled astrophysicists for 45 years. …
