This is not an actual image of a black hole. This artist’s impression shows the surroundings of a supermassive black hole, typical of that found at the heart of many galaxies. The black hole itself is surrounded by a brilliant accretion disc of very hot, infalling material and, further out, a dusty torus. There are also often high-speed jets of material ejected at the black hole’s poles that can extend huge distances into space. Illustration and caption by European Southern Observatory

LIGO found hints that at least one black hole in the system called GW170104 was non-aligned with its orbital motion before it merged with its partner.
