"When it comes to unlocking the secrets of the universe, sometimes the devil is in the static. In the 1960s, scientists trying to find a source of radio interference discovered the microwave background radiation—extremely faint embers left over from the heat of the big bang that pervade the entire night sky. Now two physicists attempting to overcome some unexpected fuzziness in images of distant, supermassive black holes say they have found yet another potential big bang vestige: an extremely weak magnetic field that stretches across the universe. If scientists confirm the finding, it could help reveal the origins of magnetism in the cosmos.
