Scientists have begun to piece together the origin story of a cataclysmic collision between two black holes that met their fate on an unusual orbital path. The merger, designated GW200208_222617 (that really rolls of the tongue,) stands out among gravitational wave detections as one of the rare events showing clear signs of orbital eccentricity, meaning the black holes followed a squashed, oval shaped orbit rather than a circular one as they spiralled toward their final encounter.
