Neutron stars are ultra-dense star remnants made up primarily of nucleons (i.e., protons and neutrons). Over the course of millions of years, these stars progressively cool down, radiating heat into ...

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 ...

Quantum computing and neutron star physics are converging on the same hard problem: how to describe matter when gravity and quantum mechanics both refuse to stay in the background. Researchers are ...

As the collapsed core of a massive star, a neutron star is a small but incredibly dense object, packing up to three times the mass of our sun into a small volume. Models predict that neutron stars are ...

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 ...

Binary neutron star mergers, cosmic collisions between two very dense stellar remnants made up predominantly of neutrons, have been the topic of numerous astrophysics studies due to their fascinating ...
