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 ...

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 ...

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

In a first-of-its-kind discovery, astronomers claim they have directly measured the magnetic fields of multiple planets beyond our solar system — potentially providing a crucial new tool in the search ...

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 ...

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 ...

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 ...
