Since they were first detected in 2007, fast radio bursts (FRBs) have been a source of mystery to astronomers. In radio astronomy, this phenomenon refers to transient radio pulses coming from distant sources that typically last a few milliseconds on average. Despite the detection of dozens of events since 2007, scientists are still not sure what causes them - though theories range from exploding stars, black holes, and magnetars to alien civilizations.
