Earth's skies pulse in sync with the sun's solar flares Hidden in the chemical composition of ancient rocks are clues that Earth's magnetic field is a dynamic, shifting phenomena.

Earth’s magnetic field is generated by what’s called a “dynamo effect.” Earth isn’t the only planet with a magnetic field – gas giant planets like Jupiter have a conducting metallic ...

Artifacts from the Iron Age have revealed an intense historical magnetic anomaly in the Middle East. Could using a similar approach elsewhere help us unravel the mysteries of Earth's magnetic field?

The magnetic field radiates around the world and far into space, but it is set by processes that happen deep within the Earth's core, where temperatures exceed 5,000-degress C. New research from ...

Unexpected Metal Flow Challenges Theories Of How Earth's Magnetic Field Forms A bold experiment shows a dramatic improvement in our understanding of the planet beneath our feet. Dr. Alfredo Carpineti ...

Earth's magnetic field protects from solar radiation. It originates from molten core motion. Magnetic north pole moves constantly. Field reversals occurred in the past. The field weakens in some areas ...

Mercury does have a weak magnetic field, but it is only 1.1% as strong as Earth's and doesn't do much to shield the planet from solar radiation.

"The Earth is a ball magnet that we’re surrounding with fast-moving metal trash." "People like Elon Musk and Jeff Bezos repeatedly state that space is the key to human longevity," Solter wrote.

The magnetic dust from re-entering satellites, on the other hand, accumulates much lower — about 37 to 50 miles (60 and 80 km) above Earth's surface.

Strength of the magnetic field at Earth's surface. (ESA) The last such cataclysmic event occurred about 41,000 years ago, leaving a signature in the Laschamps lava flows in France.

A reduced magnetic field could expose satellites to high levels of radiation and solar storms, which could knock them out of the sky, Solter-Hunt said. "It's a real Catch-22 for satellite ...
