Flashes in the sky: Cosmic radio bursts point to cataclysmic origins in the distant universe



An international team of researchers including scientists from the Max Planck Institute for Radio Astronomy in Bonn have detected burst of radio waves that appear to have originated billions of light years away - when the Universe was just 6 to 9 billion years old. The researchers are still baffled about the origins of these emissions. In the future, they intend to use these flashes to probe the intergalactic space.

Four Fast Radio Bursts or FRBs with durations of only a few milliseconds were detected at high Galactic latitudes in the southern sky. The extremely short duration of the bursts and the inferred great distance imply that they have been caused by some cataclysmic cosmological event, such as two merging neutron stars or a star dying or being swallowed by a black hole.
