Earth's magnetic field is generated by the churn of its liquid nickel-iron outer core, but it is not a constant feature.

Earth’s magnetic field is easy to forget. It doesn’t make noise, it doesn’t flash, and it doesn’t ask for attention. Yet it ...

The blobs lie at the base of Earth’s mantle, around 1,802 miles beneath Africa and the Pacific.

Earth's magnetic field dramatically flipped roughly 41,000 years ago. Now you can actually 'hear' this epic upheaval, thanks to a clever interpretation of information collected by the European Space ...

While we have sent probes billions of kilometres into interstellar space, humans have barely scratched the surface of our own ...

Two enormous, supercontinent-sized 'islands' buried deep within the mantle have been revealed to have fundamental differences—contrary to previous assumptions—and they may even lead to Earth's ...

Add Yahoo as a preferred source to see more of our stories on Google. Earth's magnetic field is like an invisible shield that protects our planet from solar and cosmic radiation. While it might not be ...

Ancient volcanic rocks reveal how two giant hot regions beneath Africa and the Pacific have shaped Earth's magnetic shield.

The solar wind flows around Earth's magnetic field. A new NASA study suggests that the amount of oxygen in the atmosphere and strength of the magnetic field have been correlated for more than half a ...

Lunar rocks are famously dry. They contain almost none of the volatile elements that easily escape into space, such as hydrogen, carbon, nitrogen, and light noble gases. Yet those same elements appear ...

BepiColombo is slowly uncovering more and more fun facts about Mercury as it continues its preliminary mission. One of the ...
