Tiny bits of Earth’s atmosphere have been drifting to the moon for billions of years, guided by Earth’s magnetic field.

The post New Data From ESA’s Swarm Satellites Show Changes In The Earth’s Magnetic Field first on TwistedSifter. Since 2013, ...

It used to be thought that there were more volatiles than expected in lunar soil because they escaped Earth before it had a stable magnetic field. Researchers who ran simulations of these atmospheric ...

A magnetometer is a device that measures magnetism: the direction, strength, or relative change of a magnetic field at a ...

Like Earth, Mars once had a strong magnetic field that shielded its thick atmosphere from the solar wind. But now only the magnetic imprint remains. What's long baffled scientists, though, is why this ...

Axions are hypothetical light particles that could solve two different physics problems, as they could explain why some ...

Artifacts from the Iron Age have revealed an intense historical magnetic anomaly in the Middle East. Could using a similar approach elsewhere help us unravel the mysteries of Earth's magnetic field?

Computer simulation of a one-sided magnetic field on early Mars based on data from a study led by the University of Texas Institute for Geophysics. The study could explain the unusual magnetic imprint ...
