Primordial magnetic fields may help explain why measurements of the universe’s expansion do not agree. Scientists have long known that the universe is expanding, yet there is still no agreement on how ...

Repeated impacts can create minerals that lock in magnetic signals long after the Moon’s global field has disappeared.

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 ...

Deep beneath the surface of the sun lies a razor-thin transition zone called the tachocline. Despite being only a sliver in size, the tachocline is believed to be the engine room of the un’s magnetic ...

Jupiter and Saturn are the two largest planets in our solar system, and both are surrounded by dozens—even hundreds—of moons.

Strange magnetic surges above the Moon have baffled scientists for years. A new model points to an unexpected plasma interaction as the culprit.

Twentieth-century explorations answered many questions about our satellite and its place in the solar system. But they also raised many new and challenging questions that still remain unanswered. One ...

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 ...

Jupiter's strong magnetic field formed a disk cavity, trapping multiple large moons. Saturn's weaker field lacked this, ...

Add Yahoo as a preferred source to see more of our stories on Google. You may have seen headlines or social media posts talking about a weakening of Earth’s magnetic field, specifically over the South ...
