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 ...

In 2020, astronomers discovered a violent cosmic event that has led them to rethink how extreme pairs of astronomical objects form. These pairs are capable of producing powerful cosmic collisions.

Astronomers analyzing the gravitational-wave event known as GW200105 report evidence that a black hole and neutron star ...

Physicists have found a new “island of inversion” in the nucleus of molybdenum-84, a perfectly balanced atom with equal numbers of protons and neutrons. The discovery upends a decades-old assumption ...

Astronomers have tracked a powerful blast of radiation back to its source, finding a neutron star collision within colliding galaxies.

Physicists have discovered a surprising new “Island of Inversion” in a place no one expected: among nuclei where the number ...

Scientists analyzing a gravitational-wave signal have discovered that a neutron star and black hole spiraled together on an oval-shaped orbit just before merging. This unusual motion, detected in the ...

Scientists have uncovered the first robust evidence of a black hole and neutron star crashing together but orbiting in an oval path rather than a perfect circle just before they merged. This discovery ...

Researchers said this event, called GRB 230906A, is likely in a stream of gas located about 4.7 billion light-years from Earth.

For more than 60 years, the High Flux Isotope Reactor has produced neutron beams for the benefit of society, creating real-world impacts that span energy security, quantum computing, healthcare, ...

One of the four missions at DOE’s High Flux Isotope Reactor is neutron scattering, a research technique used to study matter at the atomic scale. These neutrons are produced at HFIR through fission, ...
