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 ...

Research shows Earth’s magnetic field may have formed with a fully molten core - protecting the planet long before the inner ...

The region of space dominated by Earth's magnetic field is the magnetosphere. Observations have shown that, within this ...

About 41,000 years ago, Earth’s magnetic field briefly flipped in what is known as the Laschamp event. Now, a group of scientists using data from the European Space Agency’s (ESA) Swarm ...

Earth’s magnetic field is a dynamic system generated by turbulent motions in the liquid outer core. These convective processes, modulated by Earth's rotation, arise from complex interactions ...

The magnetic field is not something that is static. The Earth’s magnetosphere is being altered by the solar wind coming from the Sun. During periods of high activity, like now, it is squished ...

As Earth warms, much of the extra heat is stored in the planet’s ocean — but monitoring the magnitude of that heat content is a difficult task. A surprising feature of the tides could help ...

The Earth’s magnetic field has been weakening for 2,000 years, and that trend continues today, leading some to worry that it may be heading for a reversal. Although the idea of an impending magnetic ...
