Describing matter under extreme conditions, such as those found inside neutron stars, remains an unsolved problem. The ...

Neutron stars are ultra-dense star remnants made up primarily of nucleons (i.e., protons and neutrons). Over the course of ...

A double blast of dying stars may be the first observed case of a long-hypothesized, never proven “superkilonova.” Although ...

Neutron stars—the dense remnants of massive stellar explosions—and their presence in X‐ray binaries serve as natural laboratories for extreme physics. In these systems, matter is transferred from a ...

Neutron stars are what remain after giant stars collapse, leaving behind a body so dense that its core crushes protons and neutrons into a tightly packed soup. These objects cool very slowly over ...

Magnetars are surrounded by the most powerful magnetic fields in the known universe, but these dead stars are also surrounded by plenty of mystery. And now, thanks to the Hubble Space Telescope and ...

The field of astrophysics continues to probe the extreme regimes of matter and gravity through studies of neutron stars and black holes. These compact objects, forged in the aftermath of stellar ...

Ground-based radio telescopes, gravitational wave detectors, and a space-based X-ray telescope (right) all measure neutron stars (top left, shown merging), lending insight into the pairing of ...

It weighs more than 2 times the mass of our sun, but is only 18 miles wide. Astronomers have discovered the "most massive neutron star ever measured," amassing to more than two times the mass of our ...

Scientists have discovered a new way to probe the interiors of neutron stars by using gravitational waves to turn them into "cosmic tuning forks." The reverberations of such ripples in spacetime could ...
