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

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 final dance of a black hole and a neutron star before their ultimate merger has been revealed, according to new research.

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.

Some of the universe’s densest objects can twist, stretch, and resonate in ways that challenge even the most seasoned ...

The mystery of superluminous supernovae has finally been solved, as researchers have conclusively linked these cosmic phenomena to magnetars.

The catastrophic collision of a black hole and a neutron star sent ripples across the universe. New analysis of those ripples could upend a major theory about how these extreme pairs form.

Neutron stars harbor some of the most extreme environments in the universe: their densities soar to several times those of ...

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

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 ...

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