A new analysis of the neutron star merger known as GW170817 has delivered the most precise measurement yet of the Hubble ...

Second only to black holes, neutron stars—incredibly dense star remnants—are the densest objects in the universe. When ...

Neutron stars, the remnants of massive stars after a supernova, are among the densest and most fascinating objects in the universe. Recent discoveries have indicated that some neutron stars are ...

A Chinese research team has for the first time detected radio pulses from a long-term "radio-quiet" young neutron star - ...

Neutron star mergers are collisions between neutron stars, the collapsed cores of what were once massive supergiant stars. These mergers are known to generate gravitational waves, energy-carrying ...

A neutron star is the collapsed core of a massive supergiant star, which had a total mass of between 10 and 25 solar masses, possibly more if the star was especially metal-rich. Except for black holes ...

Ultra-dense corpses of former stars, known as neutron stars, spin very, very fast. They also sometimes “glitch,” or speed up for no reason. A team of European quantum physicists and astronomers ...

Forget archaeologists and their lost civilizations, or paleontologists with their fossils—astrophysicist Heloise Stevance studies the past on an entirely different scale. When astronomers catch a ...

Strange matter only occurs under very specific circumstances -- and astrophysicists are getting closer to understanding what ...

Sometimes astronomers come across objects in the sky that we can’t easily explain. In our new research, published in Science, we report such a discovery, which is likely to spark discussion and ...
