Neutron stars are some of the weirdest cosmic objects, and the greatest mysteries lie deep in their hearts. Neutron stars are the leftover cores of exploded stars and the densest known material in the ...

Between May 2023 and January 2024, a global network of gravitational-wave detectors picked up 128 new cosmic signals, more ...

A newly analyzed gravitational-wave event has revealed something unexpected about one of the Universe’s most violent encounters. Scientists have found the first strong evidence that a black hole and a ...

These provide statistical insights into the collisions between the incredibly compact objects that cause them, whether ...

Astronomers have tracked a powerful blast of radiation back to its source, finding a neutron star collision within colliding galaxies.

Gold was not born on our planet Earth; it was forged in a violent ‘cosmic forge’ far beyond our solar system. Research ...

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 ...

You might owe that gold necklace around your neck to a moody, long-dead star from the universe’s ancient past. According to a new study, magnetars—a rare type of neutron star—may have forged some of ...

"We are really pushing the edges, and are seeing things that are more massive, spinning faster, and are more astrophysically interesting and unusual." When you purchase through links on our site, we ...

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

These are neutrinos, the "ghost particles" of astrophysics. Almost all of them pass through everything in their path without leaving a trace. But deep inside ...
