A decade ago, scientists first detected fast radio bursts (FRB). They’re so-called because they’re incredibly powerful bursts of radio signals, but they’re extremely short-lived: a few milliseconds in length. Last year, scientists finally managed to catch one happening in real-time. And now we’ve managed to pinpoint where a repeating signal – FRB 121102 – is coming from. What is causing it is still open to speculation.
