The inset illustration shows high-energy particles in the jet (blue). When the particles hit the shock wave, depicted as a white bar, the particles become energized and emit X-rays as they accelerate.

A binary black hole ( BBH ), or black hole binary, is a system consisting of two black holes in close orbit around each other.

Black holes and galaxies are closely connected, as every galaxy is thought to have a supermassive black hole at its center. The black hole's immense gravity helps to shape and hold together the galaxy, while the galaxy's rotation also affects the black hole's growth and behavior. 3. Russell and his colleagues looked at a well-studied outburst of the black-hole binary XTE J1550-564. The system lies 17,000 light-years away in the southern constellation of Norma and contains a black hole with about 10 times the sun’s mass. The usually inconspicuous binary was discovered by RXTE in 1998, when the system briefly became …
