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 ...

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

Pegasi b Fellow Sarah Steele will spend three years at UC Santa Cruz working with Earth and planetary scientists to advance ...

Like Earth, Mars once had a strong magnetic field that shielded its thick atmosphere from the solar wind. But now only the magnetic imprint remains. What's long baffled scientists, though, is why this ...

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 ...

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 ...

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 ...
