For years, NASA has monitored a strange anomaly in Earth's magnetic field: a giant region of lower magnetic intensity in the ...

Artifacts from the Iron Age have revealed an intense historical magnetic anomaly in the Middle East. Could using a similar ...

Boldly etched into the flow of solidifying lava across Earth, the Matuyama-Brunhes event is used by geologists as a marker of ...

At its lowest point, the field strength fell to below 10 percent of today’s levels, leaving Earth exposed to dangerous cosmic radiation and solar winds. Usually, the magnetosphere acts as a protective ...

The visualization above shows the magnetic field around Earth — the magnetosphere — as it might look from space. This view is conceptual, but based on real science observations that have been ...

If the poles were to reverse, Earth's magnetic field would dip to 20% strength, possibly for centuries. Such an event would plunge our current global communications system into disarray.

An illustration of Earth's magnetic field, the Earth, the solar wind, the flow of particles. Research suggests the magnetic field nearly collapsed around 600 million years ago, and that may have ...

The Earth’s magnetic field reverses on time scales that vary between 100,000 to 1,000,000 years. Scientists can tell how often the magnetic field reverses by looking at volcanic rocks in the ocean.

These rocks offer evidence that Earth had a strong magnetic field 3.7 billion years ago, but scientists aren't sure where that field could've come from.

Earth’s magnetic field is formed by the movement of the liquid metal, which is generated by the heat that escapes from the core. NOAA NCEI and CIRES. Over the past five years, ...

Earth’s Magnetic Field Might Weirdly Be Controlling the Air We Breathe, Scientists Say Magnetism and oxygen may intrinsically influence each other, but experts aren’t sure why. By Darren Orf ...

Bogong moths undertake long-distance migrations to ancestral summer caves, using both Earth's magnetic field and the stars as navigational aids. This dual-compass system enables precise ...
