The LIGO-Virgo-KAGRA international network of Gravitational Wave observatories announced the discovery of an exceptional astronomical event. The event is named GW250114, as it was detected on January 14, 2025 by the LIGO Livingston and Hanford Observatory in the U.S. The black holes were strikingly similar (in their masses and distance) to those observed in LIGO’s first detection, in 2015: GW150914. But, after 10 years of improvements to both the global network of gravitational-wave detectors and the methods used to analyze their data, LVK researchers were able to “hear” GW250114 three times as clearly as that pioneering first detection. With this unprecedented observation, LVK researchers have confirmed that black holes only ever grow in size conjectured by Stephen Hawking and Jacob Bekenstein and, when disturbed, they ring like a bell with the “sound” predicted by Einstein.
