New Delhi, July 5 -- The universe produced at least three to four gravitational wave events every week for most of the past two years, and astronomers have just published the complete accounting. The LIGO-Virgo-KAGRA (LVK) collaboration unveiled GWTC-5.0, the fifth edition of the Gravitational Wave Transient Catalog, on May 26, cataloging 161 newly identified signals from colliding black holes detected between April 10, 2024 and January 28, 2025. That pushes the total count of confirmed gravitational wave detections to 390 since the first was recorded in September 2015.
