A strange flash in a distant galaxy first looked like a familiar kind of stellar wreckage, the radioactive afterglow of ...

Describing matter under extreme conditions, such as those found inside neutron stars, remains an unsolved problem. The density of such matter is equivalent to compressing around 100,000 Eiffel Towers ...

A strange double flash in a distant galaxy may be the first glimpse of a “superkilonova,” a cosmic one‑two punch that fuses ...

The collision of two neutron stars around 130 million light-years from Earth, and the unique physics this merger created, may have shed new light on dark matter. Axions have never been directly ...

"It is fascinating to concretely see how each new neutron-star observation enables us to deduce the properties of neutron-star matter with increasing precision." When you purchase through links on our ...

Neutron stars are ultra-dense star remnants made up primarily of nucleons (i.e., protons and neutrons). Over the course of millions of years, these stars progressively cool down, radiating heat into ...

"Our research establishes a strong link between quantum mechanics and astrophysics and provides a new perspective on the inner nature of neutron stars." When you purchase through links on our site, we ...

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 ...

The LIGO/VIRGO/KAGRA collaboration searches the universe for gravitational waves produced by the mergers of black holes and neutron stars. It has now announced the detection of a signal indicating a ...

EVANSTON, Ill. (CBS) -- Northwestern University astrophysicists were among those involved in an international research collaboration that has detected a gravitational-wave signal caused by a merger of ...
