As binary neutron stars spiral around each other to merge, their gravitational tidal forces distort each other's shape and ...

Physicists at Goethe University in Frankfurt, Germany, have used supercomputer simulations to predict a specific gravitational-wave fingerprint that would confirm quark-gluon plasma forms inside the ...

Some of the universe’s densest objects can twist, stretch, and resonate in ways that challenge even the most seasoned physicists. Neutron stars, the remnants of massive stars that have exploded as ...

Scientists may soon see inside neutron stars, potentially revealing a state of matter, quark-gluon plasma, last seen immediately after the Big Bang.

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 ...

Neutron stars harbor some of the most extreme environments in the universe: their densities soar to several times those of atomic nuclei, and they possess some of the strongest gravitational fields of ...

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 ...

A research team is using astrophysical explosions to understand the mysterious forces at work in some of the smallest ...

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

Using NASA’s Chandra X-ray Observatory and other telescopes, astronomers have traced a short-duration gamma-ray burst event called GRB 230906A to a faint dwarf galaxy embedded in a vast stream of ...

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 ...

The discovery of a newborn magnetar inside a distant supernova helps explain why some stellar explosions shine far brighter ...
