Like a shaggy dog in springtime, some black holes have to shed. New computer simulations reveal how black holes might discard their magnetic fields. Unlike dogs with their varied fur coats, isolated ...

It's well established that the universe is expanding, but there's serious disagreement among scientists over how fast it's happening.

Some bacterial species possess an astonishing ability: They use Earth's magnetic field to orient themselves. To better understand this mechanism, the team led by Argovia-Professor Martino Poggio from ...

Enceladus’s geysers power vast electromagnetic wave systems that redistribute energy throughout Saturn’s magnetosphere.

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 ...
