How does a black hole generate a magnetic field and how can it be measured and visualized? Alan Croft Seattle, Washington As black holes feed, they pull material into a disk around them. The material ...

Numerical simulations provide a mechanism that explains how celestial objects such as stars and galaxies can generate ordered, macroscopic magnetic fields. The mechanism arises from turbulence — ...

Deep in the core of most galaxies, hidden by spinning clouds of gas and dust, black holes spin like cosmic engines. These giants — some are billions of times heavier than our sun — can shoot out ...

Magnetic fields play an important—if sometimes underappreciated—part in planetary systems. Without a strong magnetic field, planets can end up as a barren wasteland like Mars, or they could indirectly ...

Driving an electric current through a molecule can create a magnetic field. Yet in practice, such fields are often too weak ...

a) In a weak magnetic field, broad cyclotron orbits suppress the orbital contribution, allowing spin polarization to dominate, (b) In strong magnetic fields, tight cyclotron orbits enhance orbital ...

Scientists at the University of Oxford have finally settled a decades-long mystery about the Moon’s magnetic field — and it turns out both sides were right. By reanalyzing Apollo mission rocks, they ...

Magnetic fields are a fundamental part of the universe. They govern how small particles – the building blocks of planets, stars, and ultimately galaxies – move through space. We still don’t know how ...

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 ...
