Called a “fast radio burst” the signal lasted a few milliseconds but it gave off as much energy as the sun does in a day said Daniele Malesani astrophysicist at the Dark Cosmology Center University of Copenhagen. Whatever caused the cosmic radio burst must be cataclysmic huge and at least 5.5 billion light years from Earth astronomer Emily Petroff of Swinburne University told New Scientist. Another possible source of the cosmic radio waves is a phenomenon called a “blitzar.” Blitzars are supermassive neutron stars that should have become a black hole but they are spinning so fast they are temporarily prevented from collapsing.
