Merging black holes and neutron stars have unusual oval orbits prior to colliding and merging, which challenge the laws of ...

We all know how weird black holes are, but did you know there is another type of star that is just as strange? Welcome to the universe of neutron stars.

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

Scientists analyzing a gravitational-wave signal have discovered that a neutron star and black hole spiraled together on an ...

Magnetars are some of the most extreme objects in the universe. A special class of neutron stars, they are celestial bodies that pack the mass of the Sun in a sphere the size of a city. On top of that ...

Astronomers analyzing the gravitational-wave signal from a 2020 collision between a black hole and a neutron star report ...

Scientists have uncovered the first robust evidence of a black hole and neutron star crashing together but orbiting in an ...

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

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

A recently detected flash of energy appears to have emanated from the wreckage of colliding galaxies, according to an international team of astronomers led by Penn State scientists. The burst, known ...

Scientists believe this long stream of gas may have formed when several galaxies collided millions of years ago.

A fleet of NASA missions has likely uncovered a collision between two ultradense stars in a tiny galaxy buried in a huge stream of gas. Astronomers have never seen this type of explosive event in an ...
