and colleagues have detected a long-duration gamma-ray burst near the center of an old galaxy for the first time. This location is so exceptional as to suggest a third possibleway of creating these long gamma-ray bursts. In addition to the collapse of a massive star, and a merger of binary stars at the end of their lives, this paper suggests the collision of two independent neutron stars as the origin of the gamma-ray burst.
