Canadian Scientists Record Second Repeating Radio Burst From Outside Our Galaxy
The repeating burst was among 13 fast-radio bursts (FRB) recorded by a radio telescope in the Okanagan Valley. The telescope, which resembles a set of skateboarding half-pipes, was built as part of the Canadian Hydrogen Intensity Mapping Experiment (CHIME) to record radio signals from outer space.
FRBs are flashes of radio waves that last just milliseconds before disappearing; the signals originate from unknown sources outside the Milky Way, though theories range from black holes and stars producing magnetic fields to extraterrestrials. The first FRB was recorded in 2001 and identified in 2007, while the first repeating FRB was detected in 2012.
