A rare geological event occurs every 300,000 years or so: the Earth’s magnetic poles flip. The magnetic poles are the two ...

Mysterious shock wave CRACKS Earth's magnetosphere that protects our planet from dangerous space radiation. A shock wave barreled into Earth's magnetic field and cracked its magnetosphere, which ...

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 of weak magnetism appears to be splitting ...

Geologic records reveal that magnetic field strength and oxygen levels rise and fall together, implying deep-Earth processes ...

Beneath the bogs of New Zealand’s Northland is a massive Ngāwhā kauri, living from 41,000 to 42,500 years ago, which gives an isolated, unbroken record of a period when Earth’s magnetic field declined ...

So-called cracks in the Earth's magnetic field have led to spectacular aurora light shows being seen in the skies, despite there not having been a solar storm to generate them.. According to ...

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 ...

Unlike the geographic North Pole, which marks a fixed location, the magnetic north pole’s position is determined by Earth’s magnetic field, which is in constant motion.

The oldest firm age yet for Earth's magnetic field suggests that it developed before a solid planetary core, 3.7 billion years ago. When you purchase through links on our site, we may earn an ...

The mystery of why Mercury's magnetic field is so weak may just have been solved: It is being stifled by the solar wind, researchers think. IE 11 is not supported.

During a brief but dramatic chapter in Earth's history about 41,000 years ago, the planet’s magnetic field nearly collapsed. What followed was a cascade of environmental and biological changes ...

For the study, the researchers used a combination of spacecraft data obtained from NASA’s Juno spacecraft, ground observations obtained from the Keck Observatory, and computer modeling to analyze how ...
