The Earth's magnetic field and oxygen evolved together over 540 million years, according to a major NASA study.
A view of the center of our galaxy shows the Sagittarius C (Sgr C) region, where cold dust (magenta) and warmer gas and dust (cyan) surround a cluster of massive stars. The stars generate high-speed ...
Geophysicists have modeled how Earth’s magnetic field could form even when its core was fully liquid. By removing the effects of viscosity in their simulation, they revealed a self-sustaining dynamo ...
New research reveals how cryptochromes, magnetite, and electromagnetic induction help animals detect magnetic cues and find ...
Our planet’s magnetosphere has seen dramatic shifts across its history—even total reversals—but this recent wrinkle doesn’t ...

Pigeons Rely on the Earth’s Magnetic Field to Navigate. Now, Researchers May Have Uncovered How They Do It
The vestibular system, a set of structures in the inner ears that helps with balance, may grant the birds their special ability ...
Just as the amplified magnetic field peaked, these electrons settled again, locking in the strong field’s direction. Benjamin Weiss, an MIT professor and study co-author, explains the process like ...
