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 ...

Columbia Professor Brian Metzger helped other astronomers interpret their observations of the unexpected stellar event.

Neutron stars are formed when giant stars run out of fuel. Their internal pressure is no longer sufficient to fight gravity, and the resulting collapse and supernova explosion leaves a tiny core, with ...

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 ...

Neutron stars are what remain after giant stars collapse, leaving behind a body so ...

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 ...

Alfredo has a PhD in Astrophysics and a Master's in Quantum Fields and Fundamental Forces from Imperial College London.View full profile Alfredo has a PhD in Astrophysics and a Master's in Quantum ...

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 ...

A small star named M82 X-2 breaks physical barriers, as NASA's NuSTAR confirms it shines 10 million times brighter than the ...

Primordial nucleosynthesis during the early universe generated hydrogen, helium, and minor lithium-7 before the cosmos cooled, halting further fusion. Stellar interiors synthesize elements up to iron ...

Why are the jets emitted by black holes or neutron stars always concentrated like a laser? Craig CaseTwain Harte, California Astrophysical jets are rapid outflows from a central object that become ...

If you approached a neutron star, you would be instantly crushed by gravity and fried by X-rays, while your very atoms would be torn apart by magnetic fields and gravity – making you a splattered ...
