Bright Radio Bursts probe Universe’s Hidden Matter

The intensity of FRB 150807 at different radio frequencies or colors -- red corresponds to lower frequencies and blue to higher frequencies. The x-axis is time. The fine structure in the burst is the scintillation or twinkling--the rays interfere constructively and destructively differently at different frequencies. This pattern provides insights into the turbulence in plasma towards the burst. Credit: Courtesy of V. Ravi/Caltech

Fast radio bursts, or FRBs, are mysterious flashes of radio waves originating outside our Milky Way galaxy. A team of scientists has now observed the most luminous FRB to date, called FRB 150807...
