Some of the universe’s densest objects can twist, stretch, and resonate in ways that challenge even the most seasoned physicists. Neutron stars, the remnants of massive stars that have exploded as ...

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

A faint hum of gravitational waves rippling across the cosmos is now telling scientists what no telescope could show them: the dense, hidden structures buried at the centers of galaxies. A team of ...

The results reveal that our universe is reverberating with cosmic collisions. Some of the waves stem from pairs of black ...

The catalog of gravitational waves "heard" by LIGO, KAGRA and Virgo has doubled with detections of spacetime ripples.

LISA is set to revolutionize our understanding of the gravitational universe and the interactions that make the entire cosmos turn. Reading time 6 minutes LISA, a $1.6 billion gravitational wave ...

A subtle gravitational-wave “hum” from merging black holes may help settle the cosmic fight over how fast the universe is ...
