Scientists convert Earth's magnetic field collapse from 41,000 years ago into chilling audio, revealing ancient cosmic ...

Main image, an illustration shows the Earth's magnetic field. Inset, prehistoric aquatic animals. A weakening in the magnetic field may have triggered an increase in oxygen concentrations on Earth ...

Magnetic field data collected by ESA's Swarm satellites and other sources has been coverted into these frightening sounds.

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, ...

Every breath we take in contains 21% oxygen, the gas that makes life on Earth possible. Oxygen, in its combined oxide state, ...

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.

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.

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.

An illustration of Earth’s magnetic field. Solar material and energy gets funneled towards the poles where it can create auroras. NASA's Goddard Space Flight Center ...

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.

New NASA research demonstrates that 540 million years of Earth’s magnetic field changes have corresponded to surface ...
