Our readers agree that in the unlikely event you were able to approach a neutron star, it would look very smooth and bright ...

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 ...

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 ...

Mon., June 23, 2025 A composite image of the supernova 1E0102.2-7219 contains X-rays from Chandra (blue and purple), visible light data from VLT’s MUSE instrument (bright red), and additional data ...

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

When a black hole and a neutron star finally meet, the result is cosmic carnage—and now, thanks to Caltech’s latest supercomputer simulations, we’re getting a front-row seat to the whole terrifying ...

The collision and merger of two neutron stars—the incredibly dense remnants of collapsed stars—are some of the most energetic events in the universe, producing a variety of signals that can be ...

In a major breakthrough, scientists have simulated in unprecedented detail how a neutron star cracks just seconds before being swallowed by a black hole. The simulation, led by Caltech astrophysicist ...

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

New data is telling us that Neutron stars may make one of the most popular dark matter candidates. Neutron stars aren't dark matter--we figured that out a while ago. But new research is telling us ...
