Observations of its radio emission spanning a 45-year duration show epochs of periodic brightness variations. These nearly sinusoidal brightness changes have been interpreted as evidence of orbital motion of a binary black hole. [5] The orbital separation of the two black holes is inferred to be 200 to 2000 AU.
The Milky Way and Andromeda galaxies each contain a central supermassive black hole (SMBH), these being Sagittarius A* (c. 3.6 × 10 6 M ☉) and an object within the P2 concentration of Andromeda's nucleus (1–2 × 10 8 M ☉). These black holes will converge near the centre of the newly formed galaxy over a period that may take millions of ...
The star field behind the black holes is being heavily distorted and appears to rotate and move, due to extreme gravitational lensing, as space-time itself is distorted and dragged around by the rotating black holes. [1] A binary black hole (BBH), or black hole binary, is a system consisting of two black holes in close

Scientists have got a peek at what is happening inside of black holes. A new model – built on gravitational waves that were first detected almost 10 years ago – indicates what is going inside ...
Any stars in the universe can collide, whether they are "alive", meaning fusion is still active in the star, or "dead", with fusion no longer taking place. White dwarf stars, neutron stars , black holes , main sequence stars , giant stars , and supergiants are very different in type, mass, temperature, and radius, and accordingly produce ...

A 2010 paper suggested that the black hole may be displaced from the galactic center by about seven parsecs (23 light-years). [79] This was claimed to be in the opposite direction of the known jet, indicating acceleration of the black hole by it. Another suggestion was that the offset occurred during the merger of two supermassive black holes.
