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 ...

Magnetic rocks with iron oxide concentrations act as natural chroniclers of Earth's past continental movements. Using small samples of rocks, scientists can isolate magnetic grains that were frozen in ...

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 ...

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 ...

The northern lights, or aurora borealis, are a stunning sight and also an indication of Earth’s magnetic field at work. The sky over Bifrost, western Iceland, glows with the lights. Earth’s magnetic ...

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 ...

A scientist has discovered a method for detecting and better defining meteorite impact sites that have long lost their tell-tale craters. The discovery could further the study of not only Earth's ...
