Samples to be retrieved by future moonwalkers in NASA’s new Artemis program should yield even more clues. Four Artemis astronauts are expected to fly around the moon in a crucial test flight, blasting ...

The lunar rocks collected by Apollo astronauts suggested the moon had a strong magnetic field. A new analysis shows the opposite.

Learn how titanium-rich lunar rocks and Apollo landing sites reshaped researchers’ understanding of the Moon’s early magnetic history.

Learn how some of Earth’s magnetic field flips last longer than others, weakening our defenses against cosmic radiation.

Earth’s magnetic shield is shifting in dramatic ways. New data from ESA’s Swarm satellites show that the South Atlantic Anomaly — a vast weak spot in Earth’s magnetic field — has grown by nearly half ...

Researchers from the Department of Earth Sciences, University of Oxford, have resolved a long-standing debate about the strength of the moon's magnetic field. For decades, scientists have argued about ...

Deep inside the Milky Way, an invisible force is quietly holding everything together — its magnetic field. Now, researchers have created one of the most detailed maps ever of this hidden structure, ...

Deep beneath the ocean floor, ancient sediments hint that Earth’s magnetic field sometimes changed far more slowly than expected.

A sediment core from the North Atlantic has revealed that one ofEarth’s magnetic field reversals during the Eocene lasted far ...

Indian astronomers have investigated an ultraluminous X-ray pulsar in the galaxy NGC 4631, designated X-8. The new study, described in a paper published Feb. 16 on the arXiv preprint server, provides ...

Earth-like planets have a thin crust, a large mantle (which contains a lot of molten magma), and a core. Inside these ...
