Ancient bricks from Mesopotamia have helped confirm a mysterious anomaly in Earth's magnetic field that occurred 3,000 years ago, a new study finds. Brickmakers baked the bricks, which were imprinted ...

The Magnetic Shield That Protects Our Climate Earth is surrounded by an immense magnetic field, called the magnetosphere.

Geologists discovered ancient rocks in Greenland that preserve the oldest known traces of Earth’s early magnetic field.

The intensely hot interior of planets isn’t somewhere you’d expect to find snow, but scientists do suspect that “iron snow” falls on the Earth’s core. Now, a new study has modeled the dynamics in the ...

NASA tracks the growing South Atlantic Anomaly, revealing weak magnetic fields, potential satellite risks and some insights ...

Mercury’s core may be wearing a metal jacket. New experiments suggest the planet’s innards stay warm thanks to an insulating layer of iron sulfide, which could help to explain how the small world has ...

Traditionally, scientists believed that the charge polarity of the magnetosphere at the equator and the poles was the same, ...

A team of researchers has for the first time recovered a magnetic field record from ancient minerals for Iron Age southern Africa (between 1000 and 1500 AD). The data, combined with the current ...

Scientists have observed magnetic properties typically associated with those observed in rare-earth elements in iron. These properties are observed in a new iron based compound that does not contain ...

About 3,000 years ago in ancient Mesopotamia, brickmakers imprinted the names of their kings into clay bricks. Now, an analysis of the metal grains in those bricks has confirmed a mysterious anomaly ...
