New instrument extends LIGO's reach

Just a year ago, the National Science Foundation-funded Laser Interferometer Gravitational-wave Observatory, or LIGO, was picking up whispers of gravitational waves every month or so. Now, a new addition to the system is ...

First-ever open public alerts now available from LIGO

Two new probable gravitational waves—ripples in the fabric of spacetime caused by cataclysmic cosmic events and first predicted by Albert Einstein over 100 years ago—have been detected by the Laser Interferometer Gravitational-Wave ...

Galaxy-Sized Observatory for Gravitational Waves

(PhysOrg.com) -- Astronomers are making plans to create a galaxy-sized observatory to look for gravitational waves. The project is part of a joint effort with astronomers from Australia and Europe, who also aim to try to ...

Deciphering gravitational waves

When two black holes collide, the impact is so big that we can detect it all way here on Earth. These objects are so immense that their collisions send ripples through spacetime itself. Scientists call these ripples gravitational ...

Mass estimated for two binary pulsars

By performing timing observations, an international group of astronomers has measured the mass of two binary millisecond pulsars designated PSR J1949+3106 and PSR J1950+2414. The results could be essential in order to unveil ...

Can quantum particles mimic gravitational waves?

When two black holes collide, space and time shake and energy spreads out like ripples in a pond. These gravitational waves, predicted by Einstein in 1916, were observed for the first time by the Laser Interferometer Gravitational-Wave ...

Seeing double: Scientists find elusive giant black hole pairs

Astronomers have identified a bumper crop of dual supermassive black holes in the centers of galaxies. This discovery could help astronomers better understand how giant black holes grow and how they may produce the strongest ...
