Earth's magnetic field strength and atmospheric oxygen levels have oscillated in tandem for around 540 million years, ...

“We find that both exhibit strong linearly increasing trends, coupled with a large surge in magnitude between 330 and 220 ...

Unlike Earth, the Moon doesn't have much of a magnetic field – and yet, a strange pile of rocks on the far side seems mysteriously magnetized.

When set spinning, the setup mimics the roiling liquid iron in the Earth’s outer core, which forms electrical currents that generate the magnetic field in a process called a dynamo. His team ...

Earth’s oxygenated atmosphere and magnetic field make life possible, but scientists have discovered that there’s a hidden link between the two that’s stronger than we originally imagined.

The universe is soaked in weak-but-persistent magnetic fields. Despite decades of research, astronomers still aren't exactly sure where these magnetic fields came from. But new research suggests they ...

Mercury doesn't give up its secrets easily. The smallest planet in our solar system is also one of the most extreme—a ...

Anywhere with a weak dynamo and a history of large impacts might have followed a similar magnetic path. For now, though, the moon holds the clearest clues, waiting in silent rock layers for the ...

Scientists discover hidden "ghost plume" beneath Oman using earthquake data, revealing Earth's secret heat pathways.

This explorer spacecraft is heading to a rare asteroid with a naked metal core. It could hold clues to how Earth began ...

Imagine Earth suddenly stops spinning what happens next? From flying debris and mega-tsunamis to magnetic collapse and ...
