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

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

The Earth's magnetic field is essential to life as we know it. But it’s something we can never see – or hear, until now. In a recent study released on Oct. 10 by the European Space Agency, ...

The Earth’s magnetic field shows marked variations in the polar regions, which are more susceptible to auroral activity and geomagnetic storms. These factors may influence satellite and aircraft ...

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 ...

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 north is not static. Like an anchorless buoy pushed by ocean waves, the magnetic field is constantly on the move as liquid iron sloshes around in the planet’s outer core.

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.

Today, Earth’s magnetic field acts as a safety blanket, shielding the planet from dangerous solar wind. Without the protection of our magnetosphere, you, me and almost every other living thing ...

ANU geophysicist Professor Hrvoje Tkalčić says that the dynamics of Earth's magnetic field is an area of strong interest in the scientific community. A doughnut-shaped region thousands of ...

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 ...
