The most luminous kilonova candidate to date (short gamma-ray burst 200522A) was detected using the Hubble Space Telescope, Swift Observatory and other telescopes. A kilonova is a "the afterglow ...

Astronomers have used an X-ray spacecraft called XRISM to observe powerful winds blowing from a neutron star — the findings ...

Creating a neutron star Before you can get this ideal cosmic laboratory, a star first has to die. The end of a star’s life depends largely on its mass. Unremarkable stars like the Sun go out with a ...

In a recent breakthrough, the XRISM mission has uncovered a puzzling cosmic phenomenon—a slow, dense wind emanating from the neutron star GX13+1. This unexpected discovery, detailed in a study ...

Neutron stars are some of the weirdest cosmic objects, and the greatest mysteries lie deep in their hearts. Neutron stars' surface gravities are so intense that the largest "mountains" are only a few ...

Gamma-ray bursts (GRBs) are the most energetic and luminous explosions in the universe. However, they are fleeting and often ...

The GWTC 4.0 catalog records 128 new gravitational wave signals, revealing mergers of black holes and neutron stars detected by LIGO.

XRISM found a slow, thick wind from a neutron star, pointing to temperature as the key driver of cosmic wind behavior. The ...

The James Webb Space Telescope has uncovered a massive red supergiant star just before it exploded, finally solving a cosmic ...

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 ...
