Fast Radio Bursts: The Deepest Mystery in Modern Astronomy

For a few milliseconds, a fast radio burst releases more energy than the Sun emits in three days. Then it is gone. Astronomers detected the first one in archival data in 2007; by 2020 we had identified hundreds, some of them repeating. We now know they come from across the universe, and in one case from within our own galaxy. We still do not fully understand what makes them.
