New computer simulations suggest the first magnetic fields that emerged after the Big Bang were much weaker than expected — ...

At the right point of the orbit and stellar cycle, the star’s chromosphere brightens.

Designing predictable nuclear fusion reactors requires highly accurate computer models, yet existing simulations often ...

Magnetic fields usually kill superconductivity, but in a thin oxide interface they made it vanish, then return, opening a new ...

In a new study, scientists have mapped magnetic fields in galaxy clusters, revealing the impact of galactic mergers on magnetic-field structures and challenging previous assumptions about the ...

Numerical simulations and observational data have consistently demonstrated that accretion bursts in high-mass young stellar objects (HMYSOs) are primarily triggered by episodic accretion events ...

Ancient bricks inscribed with the names of Mesopotamian kings have yielded important insights into a mysterious anomaly in Earth's magnetic field 3,000 years ago, according to a new study. Ancient ...

More than a decade of satellite monitoring has mapped Earth's magnetic field as it subtly altered between 2014 and 2025 — and what scientists have learned is remarkable. The South Atlantic Anomaly, a ...

Earth’s magnetic field protects life from harmful cosmic radiation. But sometime between about 590 million and 565 million years ago, that security blanket seems to have been much thinner — with ...
