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

When a black hole–neutron star pair merges, it's assumed to do so while settling into a perfect circular orbit. But according to a recent study, there is now strong evidence for the first time that ...

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 ...

Billions of light years away in a remote part of the universe, two neutron stars – the ultradense remnants of dead stars – collided. The catastropic cosmic event sent light and particles, including a ...

A recently detected flash of energy appears to have emanated from the wreckage of colliding galaxies, according to an ...

A new theoretical framework shows that tidal forces in inspiraling neutron star pairs can be described through oscillation modes, opening a new path to studying ultra-dense matter using gravitational ...

When the densest objects in the universe collide and merge, the violence sets off ripples, in the form of gravitational waves ...

Neutron stars escape collapse into a black hole thanks to degeneracy pressure produced by their neutrons, which is able to fight the crushing force of gravity. What exactly lies at the heart of a ...
