Unlike Earth, the Moon doesn't have much of a magnetic field – and yet, a strange pile of rocks on the far side seems mysteriously magnetized. A new study suggests that a major cataclysm, over and ...

For decades, scientists have been trying to understand why some rocks on the moon are strongly magnetized even though the moon has no magnetic field today. Moon rocks brought to Earth during NASA's ...

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 ...

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 show ...

A technique for studying the magnetic properties of rocks developed by earth scientists at UC Davis is drawing attention from other scientists and the magnetic recording industry. A technique for ...

For decades, scientists have puzzled over why lunar rocks show signs of strong magnetism when the moon itself has no global magnetic field today. New simulations suggest the answer may lie in a ...

Rock record: visualization of the thermomagnetic behaviour of magnetite grains. (Courtesy: Imperial College London) The vortex-like structures in grains of magnetite can reliably preserve magnetic ...

Breathing quickly in the thin mountain air, my colleagues and I set down our equipment. We are at the base of a jagged outcrop that protrudes upwards out of a steep gravel slope. The muffled ...
