PARIS, France (AFP) — A mysterious object roughly 800 million light-years from Earth detected using gravitational wave sensors is either one of the smallest black holes or one of the largest neutron stars so far discovered, scientists said on Wednesday. The Advanced Virgo detector at the European Gravitational Observatory (EGO) in Italy and two wave observatories in the US discovered the object last year and calculated it to weigh around 2.6 times our own Sun.
