Where did the moon's magnetism go? Scientists have puzzled over this question for decades, ever since orbiting spacecraft picked up signs of a high magnetic field in lunar surface rocks. The moon ...

As the rocks' electrons settled back, they assumed a new orientation, in line with the momentary high magnetic field. "It's as if you throw a 52-card deck in the air, in a magnetic field, and each ...

And there are traces of ancient magnetism found on Mars and Earth’s moon. But there are also meteorites — small space rocks that have fallen to Earth — that contain hints of magnetism. Scientists say ...

NASA's Apollo missions brought back moon rock samples for scientists to study. We've learned a great deal over the ensuing decades, but one enduring mystery remains. Many of those lunar samples ...

These rocks offer evidence that Earth had a strong magnetic field 3.7 billion years ago, but scientists aren't sure where that field could've come from.

Rocks can become magnetized from the shock of an impact, a mechanism some scientists have proposed to explain the magnetization of lunar samples. But recent paleomagnetic analyses of moon rocks, as ...

Modern low-power solutions to computer memory rely heavily on the manipulation of the magnetic properties of materials.

In some places, by chance, these magnetic clusters are quite extensive, as on the Isle of Elba and Mount Ida in Asia Minor, where large outcrops retain the magnetic imprint in rocks known ...

Geologists at MIT and Oxford University have found ancient rocks in Greenland that bear the oldest remnants of Earth’s early magnetic field. The researchers determined that the rocks are about 3 ...
