ENG: A team mapping radio waves in the universe has discovered something unusual that releases a giant burst of energy three times an hour, and it’s unlike anything astronomers have seen before. Spinning around in space, the strange object sends out a beam of radiation that crosses our line of sight, and for a minute in every twenty, is one of the brightest radio sources in the sky. The team who discovered it think it could be a neutron star or a white dwarf which are collapsed cores of stars with an ultra-powerful magnetic field.
