Researchers have spotted interesting changes in the South Atlantic Anomaly, which is a region of Earth’s magnetic field that has a large dent. The area … ...
A rare geological event occurs every 300,000 years or so: the Earth’s magnetic poles flip. The magnetic poles are the two ends of the magnetosphere, which surrounds the Earth like a giant, invisible ...
The oldest firm age yet for Earth's magnetic field suggests that it developed before a solid planetary core, 3.7 billion years ago.
Earth’s magnetic field was once 30 times weaker than it is today. This change may have played a pivotal role in the blossoming of complex life, new research found.
How does a compass work in space? From the moon to Venus, here's how a compass would work beyond Earth's magnetic field.
By comparison, the magnetic north pole is the northernmost convergence point in Earth’s magnetic field, also known as the magnetosphere.
The phenomenon could mean that more auroras are visible across the northern hemisphere as the fall equinox approaches this month.
A visualization of the magnetic lines of force surrounding Earth, known as the magnetosphere. The magnetic field, thought to be generated by the movements of Earth's molten core, protects Earth ...
Geologic records reveal that magnetic field strength and oxygen levels rise and fall together, implying deep-Earth processes ...
At planetary scale, Earth’s magnetic field induces such a current, which regenerates the magnetic field, which induces more current, and so on in a self-sustaining process known as a geodynamo. German ...
