Today, I want to share with you a stunning astronomical discovery! The research team at the Purple Mountain Observatory has ...

On February 25, 2024, XRISM used its Resolve instrument to observe the neutron star GX13+1, which is the core of a once larger star that has burned out. GX13+1 is a bright X-ray source. These X-rays ...

The X-Ray Imaging and Spectroscopy Mission (XRISM) has revealed an unexpected difference between the powerful winds launching ...

Astronomers have doubled the number of black hole and neutron star mergers detected via gravitational waves in a "stellar ...

Neutron stars escape collapse into a black hole thanks to degeneracy pressure produced by their neutrons, which is able to fight the crushing force of gravity. What exactly lies at the heart of a ...

stellar collisions detected, including rare black hole–neutron star mergers, reshaping our view of star death and cosmic ...

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 ...

A decade after the first discovery, scientists have used these waves to find a unique merger, a massive binary system and a ...

Delve into the enigmatic realm of neutron stars—stellar remnants that defy our conventional understanding. Once blazing stars ...

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 ...
