The catastrophic collision of a black hole and a neutron star sent ripples across the universe. New analysis of those ripples could upend a major theory about how these extreme pairs form.

These provide statistical insights into the collisions between the incredibly compact objects that cause them, whether neutron stars or black holes. The new detections have also allowed us to find ...

Black holes are among the most extreme objects in the universe, and now scientists can model them more accurately than ever before. By combining Einstein’s gravity with realistic behavior of light and ...

Some of the brightest beacons in the universe share one hidden engine: matter falling into a black hole. As gas whirls inward, it heats up and shines. In some cases, it also blasts narrow beams of ...

An international team from China and Italy has reported a possible cosmic encore to the landmark 2017 multi-messenger ...

(Nanowerk News) Roughly twice every 12 years, from 3.5 billion light years away, the light equivalent of one trillion suns flashes in the night sky and then fades away over the next few months. It’s a ...

In 2023, astronomers detected a huge collision. Two unprecedentedly massive black holes had crashed an estimated 7 billion light-years away. The enormous masses and extreme spins of the black holes ...

Rochester Institute of Technology researchers helped pinpoint the precise location of a gravitational wave signal—and the black hole merger that produced it—detected by gravitational wave ...

Understanding how galaxies grow has long stood as one of astronomy’s core challenges. Over time, scientists have gathered evidence that galaxy mergers matter. When two galaxies move close, gravity can ...
