The LIGO–Virgo–KAGRA (LVK) collaboration has unveiled its latest catalog of gravitational-wave discoveries, adding 161 new events detected between April 2024 and January 2025 and bringing the total number of confirmed signals to 390. The new findings mark an exciting step forward for gravitational astronomy, revealing possible evidence of “second-generation” black holes - black holes formed from earlier black hole mergers and capturing the most precisely located gravitational-wave source ever observed. One particularly remarkable signal, GW250114, was also the clearest ever recorded, allowing scientists to perform the most accurate test of general relativity to date and further confirm ideas first proposed by Stephen Hawking. With improved detector sensitivity and a growing number of observations, researchers are now beginning to uncover not just individual cosmic collisions, but the broader story of how black holes form, evolve, and shape our Universe.
