Dark matter, matter in the universe that does not emit, absorb or reflect light, cannot be directly detected using conventional telescopes or other imaging technologies. Astrophysicists have thus been trying to identify alternative ...
Fast radio bursts—intense, milliseconds-long flashes of radio energy from outer space—have puzzled astronomers since they were first spotted in 2007. A single burst can emit as much energy in its brief life as the Sun ...
