An artist's conception of a precessing binary black hole. The black holes, which will ultimately spiral together into one larger black hole, are shown here orbiting one another in a plane. The black holes are spinning in a non-aligned fashion, which means they are tilted relative to the overall orbital motion of the pair. This causes the orbit to precess like a top spinning along a tilted axis.
