Astronomers using the MeerKAT telescope discovered a hydroxyl megamaser in a galactic merger 8 billion light-years away, amplified by gravitational lensing and operating at radio wavelengths.

Neutron stars harbor some of the most extreme environments in the universe: their densities soar to several times those of ...

Detecting supermassive black holes just before their merger would lead to significant advances in astrophysics. To achieve this, a new innovative approach combines the study of the gravitational ...

On the other are journalists like me who believe there is more to acknowledging the world and understanding how it works than ...

When black holes collide, the crash generates ripples in the fabric of spacetime—gravitational waves. Thanks to a global network of observatories—called the Laser Interferometer Gravitational-Wave ...

When the densest objects in the universe collide and merge, the violence sets off gravitational waves that reverberate across space and time over ...

When black holes collide, the crash generates ripples in the fabric of spacetime—gravitational waves. These distortions ...

Scientists propose a gravitational-wave method called the stochastic standard siren to measure the Hubble constant, offering an independent way to examine the universe’s expansion and the Hubble ...

When the densest objects in the universe collide and merge, the violence sets off ripples, in the form of gravitational waves, that reverberate across space and time, over hundreds of millions and ...

A mysterious striped signal from the Crab Pulsar may finally be explained by a delicate balance between plasma effects and gravitational lensing.

Ripples in the fabric of space-time called gravitational waves may be the key to solving the Hubble tension — one of the biggest nagging problems in physics.

Collaboration has published its latest compilation of gravitational-wave detections, showing the universe is echoing all over with a kaleidoscope of cosmic collisions.
