An astrophysicist explains what wormholes are and how these theoretical space-time tunnels have popped up in the solutions to a set of decadesold equations.

Scientists suspect that a rapidly spinning, highly magnetic neutron star, or "pulsar," dwells at the heart of the Milky Way.

Neutron stars are ultra-dense remnants of massive stars that collapsed after supernova explosions and are made up mostly of ...

Scientists say that while ordinary crystals repeat precisely, quasicrystals maintain order even though their patterns fail to repeat perfectly.

Quasicrystals are orderly structures that never repeat. Scientists just showed they can exist in space and time.

“Quantum sensing opens an entirely new domain for U.S. space leadership,” said Dana Anderson, Chief Science Officer at Infleqtion. “By deploying this technology in orbit, we are demonstrating the ...

Physicist Sean Carroll explains how physics, astronomy, philosophy, and classics all help us understand the expanding ...

The broadest planned survey by NASA’s upcoming Nancy Grace Roman Space Telescope will reveal hundreds of millions of galaxies scattered across the cosmos. After Roman launches as soon as this fall, ...

These changes aren’t permanent – the brain goes gradually back to normal after coming back to Earth. Understanding the ...

Gravity used to be the most dependable rule in the cosmic rulebook, the quiet background force that never changed its mind. Now a series of discoveries and bold claims are turning that certainty into ...
