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 ...

Scientists call this state of matter a quark-gluon plasma. This state of matter existed during the first fraction of a second ...

GRB 230906A, a short gamma-ray burst first detected in 2023, points to a faint galaxy embedded within a long stream of torn ...

The signal indicated that the event occurred extremely far away. The masses of the objects involved also caught scientists’ ...

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

GW200105 reveals an eccentric orbit before merger, challenging formation models.

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 ...

Neutron stars are ultra-dense remnants of massive stars that collapsed after supernova explosions and are made up mostly of subatomic particles with no electric charge (i.e., neutrons). When two ...

The end of a star’s life can be an extremely violent event. Once it runs out of fuel, its core collapses, and if its original mass is large enough, it can erupt in a supernova, a runaway nuclear ...

The Men’s Ice Hockey tournament is officially underway, and fans have already been treated to several memorable moments in the opening slate of games. One of the most talked about sequences came in a ...

Scientists have seen something spectacular unfolding in Andromeda, our neighboring spiral galaxy, located some 2.5 million light-years away from Earth. The spectacular part is actually what they ...
