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, the remnants of massive stars after a supernova, are among the densest and most fascinating objects in the universe. Recent discoveries have indicated that some neutron stars are ...

Researchers study neutron star crusts by simulating neutron matter then adding “hidden” neutrons to mediate interactions between “real” neutrons. Next, neural networks construct a quantum wave ...

Magnetars — the dense remains of dead stars that erupt sporadically with bursts of high-energy radiation — are some of the most extreme objects known in the universe. A major campaign using NASA’s ...

Right at the brink of a black hole, gravity twists space and time so violently that ordinary physics starts to fall apart. For decades, astronomers could only guess how gas, magnetic fields, and ...

Physicists have shown that extremely light particles known as axions may occur in large clouds around neutron stars. These axions could form an explanation for the elusive dark matter that ...

A huge amount of mysterious dark energy is necessary to explain cosmological phenomena, such as the accelerated expansion of the Universe, with Einstein’s theory. But what if dark energy was just an ...
