Significance Astrophysicist Sergio Campana told Space.com that he thinks this was "the discovery of a completely new astrophysical phenomenon that [had] not been envisaged before." He also said, "If tidal disruption of minor bodies around neutron stars is really happening", this event would not be "unique". Christina Thöne has said, "What the Christmas burst seems to be telling us is that the family of gamma-ray bursts is more diverse than we fully appreciate."
