  Modern astrophysics is undergoing a revolution. As detector technology has
advanced, and astronomers have been able to study the sky with finer temporal
detail, a rich diversity of sources which vary on timescales from years down to
a few nanoseconds has been found. Among these are Fast Radio Bursts, with
pulses of millisecond duration and anomalously high dispersion compared to
Galactic pulsars, first seen a decade ago. Since then, a new research community
is actively working on a variety of experiments and developing models to
explain this new phenomenon, and devising ways to use them as astrophysical
tools. In this article, I describe how astronomers have reached this point,
review the highlights from the first decade of research in this field, give
some current breaking news, and look ahead to what might be expected in the
next few years.
