 Scientists from the University of Helsinki have cracked a major cosmic puzzle! Through cutting-edge supercomputer simulations , they’ve discovered how magnetic fields around black holes cause chaotic turbulence that heats plasma and produces the X-ray radiation that we can observe from Earth. This breakthrough could change how we understand the dynamics of these mysterious cosmic giants. Visualization shows how the turbulent plasma moves in the magnetized accretion disk corona.

Though we can't see black holes directly, their influence on nearby stars and gas reveals their presence. In a binary system, black holes slowly consume their companion stars, forming a glowing disk of matter known as an accretion disk. These disks are sources of intense X-rays, helping us observe the otherwise invisible bla...

  Scientists may have found a solution to the " final parsec problem ," which has made it difficult to explain how supermassive black holes (SMBHs) form. This breakthrough points to a mysterious form of dark matter as the key to resolving the issue.

When black holes get close, they seem to orbit indefinitely instead of merging. Known as the "final parsec problem," this issue occurs when the black holes reach a separation of about one parsec (3.26 light-years) and become stuck, unable to lose enough energy to collide and merge.

The galaxy's butterfly shape was caused by the collision of two smaller galaxies.  (Image credit: ...
