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

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 ...

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 ...

Scientists may have solved the mystery of why the moon shows ancient signs of magnetism although it has no magnetic field today. An impact, such as from a large asteroid, could have generated a cloud ...

USGS and NASA have recently teamed up to create one of the most complete databases of magnetic properties of Earth’s rocks ever assembled. Satellite data of Earth's magnetic field combined with ...

Without plate tectonics, our planet wouldn’t have continents, mountains, and possibly even life itself. New evidence suggests this geological process began at least 3.2 billion years ago, a ...

The rocks retrieved by the Apollo missions have puzzled scientists for 50 years. When you purchase through links on our site, we may earn an affiliate commission. Here’s how it works. Scientists may ...

An ancient asteroid impact may be to blame. When you purchase through links on our site, we may earn an affiliate commission. Here’s how it works. For decades, scientists have been trying to ...

This photo shows an example of the 3.7 billion year-old banded iron formation found in the northeastern part of the Isua Supracrustal Belt. Geologists at MIT and Oxford University have uncovered ...

Surrounding Earth is a powerful magnetic field created by swirling liquid iron in the planet’s core. Earth’s magnetic field may be nearly as old as the Earth itself – and stands in stark contrast to ...
