Fresh observations of two merging black holes confirm predictions made by Stephen Hawking based on Albert Einstein’s theory. A decade after the first detection of gravitational waves from two merging ...

Primordial black holes (PBHs) are black holes theorized to have formed shortly after the Big Bang. Compared to black holes ...

Today the international LIGO-Virgo-KAGRA Collaboration announces the completion of the fourth observation campaign of the ...

The year 2015 was a landmark for the astrophysics community across the globe as the Laser Interferometer Gravitational-Wave ...

On Nov. 2, Kip Thorne took the stage at Harvey Mudd College’s Galileo Auditorium to recount his 50 year odyssey of making ...

A newly observed gravitational wave event from the collision of two massive, rapidly spinning black holes forces scientists to reconsider how these cosmic giants are born and grow.

Astronomers spotted the largest flare ever released from a supermassive black hole as it snacked on a giant star.

Two recently observed black hole mergers, occurring just weeks apart in late 2024, have opened an extraordinary new window into the universe’s most extreme events. These collisions not only revealed ...

The mergers, measured one month apart in 2024 by LIGO-Virgo-KAGRA collaboration, advance scientific understanding of the nature of black hole formation and fundamental physics; offer evidence of ...

One week ago, National Science Foundation Director Rita Colwell spoke at the inauguration of the Laser Interferometer Gravitational-Wave Observatory (LIGO) facility in Livingston, Louisiana. LIGO’s ...

Gravitational waves are created when massive objects accelerate in space, especially in violent events. LIGO detected the first gravitational waves when two black holes, orbiting one another, finally ...

September 2025 marks ten years since the first direct detection of gravitational waves as predicted by Albert Einstein’s 1916 theory of General Relativity. These invisible ripples in space were first ...
