Releasing that much energy requires an unfathomable furnace, and in this case that's the power of two galaxies smashing into each other to become one.

Physicists have long struggled to unite quantum mechanics—the theory governing tiny particles—with Einstein’s theory of ...

Astronomers have discovered the brightest and most distant "megamaser" to date. The cosmic energy beam is shooting toward ...

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

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.

The international network of gravitational wave detectors LIGO in the United States, Virgo in Italy and KAGRA in Japan (LVK) announced the publication ...
