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.

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 ...

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

Centuries before anyone pointed a telescope at the sky, Isaac Newton figured out how gravity works. He showed that any object with mass pulls on every other object—a result that explained falling ...

While nearly all massive galaxies possess central black holes, the presence of such black holes in dwarf galaxies remains an open question, with previous estimates identifying them in only 0.5% of ...
