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

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 ...

Although magnetic forces are usually much weaker than gravity in shaping cosmic structures, the findings suggest that strong, ordered magnetic fields may have emerged earlier than expected. Over time, ...

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 ...

"A better understanding of Saturn’s environment is especially urgent now as plans for our return to Saturn and its moon ...

"Their magnetic fields—which arise from minuscule details of the planet's makeup—can tell us a lot about their formation and evolution, and the evolution of our universe." The team will incorporate ...

Pigeons can sense Earth’s magnetic field by detecting tiny electric currents in their inner ears, a team of researchers suggests. Such an inner compass could help to explain how certain animals can ...
