Event Horizon Telescope data reveal the magnetic field around M87* shifted, weakened and then flipped, defying theoretical expectations.

Newly reported gravitational waves rang out as clear as a bell. Spotted in January, these spacetime ripples are the clearest yet discovered, cutting through the background noise better than any ...

Black holes get bigger as they merge, the LIGO Collaboration confirmed with a new observation that could finally prove a decades-old Stephen Hawking theory.

"GW250114 is the loudest gravitational wave event we have detected to date; it was like a whisper becoming a shout." The Laser Interferometer Gravitational-Wave Observatory (LIGO) is celebrating 10 ...

Ten years ago, astronomers made an epic discovery with the Laser Interferometer Gravitational-Wave Observatory. Cosmology hasn’t been the same since, and it might not stay that way much longer.
