The near-light-speed outflows are crucial to understanding galaxy-black hole co-evolution.

The research could shed light on how black holes vomit out matter and how this influences their home galaxies.

Despite years of debate and follow-up studies, an odd streak of cosmic light still defies a final explanation. Is it a giant ...

The catastrophic collision of a black hole and a neutron star sent ripples across the universe. New analysis of those ripples ...

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

The lasers alone would cost around one trillion dollars and the technology to create a nanocraft does not yet exist.

Like physics, math has its own set of “fundamental particles”—the prime numbers, which can’t be broken down into smaller natural numbers. They can only be divided by themselves and 1. And in a new ...

A newly analyzed gravitational-wave event has revealed something unexpected about one of the Universe’s most violent encounters. Scientists have found the first strong evidence that a black hole and a ...

A neutron star and black hole were detected merging along an unusual oval orbit, challenging long-held theories about how these systems form.

For decades, scientists have known black holes often come in pairs. These binary systems feature a black hole locked in a gravitational dance with a nearby object—usually a star, neutron star, or ...

An artist's concept of a tidal disruption event (TDE), which happens when a star passes close to a supermassive black hole. The gravity of the black hole pulls material from the star and launches a ...
