An entirely new field of observational astronomy was inaugurated with the operation of gravitational wave observatories in the United States in 2015 and Italy in 2017. Until recently, gravitational forces could only be inferred from the distribution and motion of astronomical objects, but now a new window is opening up on the structure of the universe. Davide Castelvecchi’s overview of the achievements of gravitational wave astronomy to date and its future development is an exciting and approachable introduction to a fascinating new frontier.
