26 Mar 2019 — LIGO is set to resume its hunt for gravitational waves—ripples in space and time—on April 1, after receiving a series of upgrades to its lasers, mirrors, and other components. LIGO now has a combined increase in sensitivity of about 40 percent over its last run, which means that it can survey an even larger volume of space for gravitational-wave events like black hole collisions.

Joining the search will be Virgo, the European-based gravitational-wave detector, located at the European Gravitational Observatory (EGO) in Italy, which has almost doubled its sensitivity since its last run and is also starting up April 1.
