London, Sept 28 : A radio burst that originated from beyond the Milky Way galaxy has befuddled astronomers.
Initial suspects include the merger of two dense stellar corpses called neutron stars and the complete evaporation of a black hole.
David Narkevic, an undergraduate student at West Virginia University in Morgantown, US, discovered the burst while searching through archived data taken in 2001 by the Parkes radio dish in Australia. He was looking for periodic signals from pulsars – rotating neutron stars – within our galaxy.
