A recent study led by NASA has revealed a surprising connection between Earth’s magnetic field and the oxygen levels that ...

This magnetic field is vital to life on Earth because it shields the planet from radiation emitted by the sun. It is generated in our planet's outer core by swirling liquid iron around 1,800 miles ...

The CME caused Earth’s bow shock—the shockwave that typically forms when a CME hits Earth’s magnetic field—to disappear for two hours, from approximately 8:30 a.m. to 10:30 a.m. ET.

Then, Earth’s core was liquid, not solid. The liquid inner core churned as it released heat into the cooler mantle, moving molten iron around the core and enabling Earth’s magnetic field to exist.

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, ...

And because the movement of Earth’s liquid metallic core creates its magnetic field, the field itself is complex — far more so than the standard Earth-as-a-bar-magnet illustrations imply.

Further, physicists like Cohen say that the Earth’s magnetic field isn’t going to flip overnight. This is something that reverses on a time scale between 100,000 and 1,000,000 years.

Earth’s magnetic field is essential to life on the planet, but it isn’t something that we can typically see or hear. It’s basically a shield that protects the planet from the cosmic ...
