Gravitational waves have been uncovered from a massive black hole merger that shows the resultant black hole settling into a spherical shape for the first time, helping test Einstein’s theory of ...

For decades, scientists have believed there should be black holes that fall between two well-known types. On one end are ...

The scientists identified the merging black holes by detecting the gravitational waves–ripples in the fabric of space-time–produced in the final moments of the merger. The gravitational waves ...

This black hole merger animation was created using data collected by the LIGO and Virgo gravitational wave detectors, an ...

And it could change how astronomers understand black holes. In August 2019, astronomers using gravitational wave detectors in the US and Italy detected ripples in space and time, a gravitational ...

In a recently published paper in Physical Review Letters, scientists propose a comprehensive theoretical framework indicating ...

Scientists say they've found evidence of a very long gravitational wave that could open a window onto supermassive black holes — and perhaps even other extreme, unseen objects in the universe.

Binary neutron star mergers, cosmic collisions between two very dense stellar remnants made up predominantly of neutrons, ...

Caltech simulations reveal what happens when black holes collide with neutron stars—violent cracking, intense shock waves, ...
