Our planet’s magnetosphere has seen dramatic shifts across its history—even total reversals—but this recent wrinkle doesn’t ...

It used to be thought that there were more volatiles than expected in lunar soil because they escaped Earth before it had a ...

A weak region in Earth's magnetic field has grown by an area roughly half the size of continental Europe in the last 10 years. That's according to data collected by the European Space Agency's (ESA) ...

It would be an understatement to say that the Earth's magnetic field is important. It's one of the reasons we're able to live on this rock tumbling through space, and it also gives us the gorgeous ...

How could such a small body with a weak core have created magnetic fields as strong as Earth’s? Now, a team led by researchers at MIT may have found the answer. Their study, published in Science ...

A weak spot in the Earth's magnetic field is growing over the South Atlantic Ocean, according to more than a decade's worth of satellite data collected by scientists. The magnetic field surrounding ...

Primordial magnetic fields, billions of times weaker than a fridge magnet, may have left lasting imprints on the Universe. Researchers ran over 250,000 simulations to show how these fields shaped the ...

a) In a weak magnetic field, broad cyclotron orbits suppress the orbital contribution, allowing spin polarization to dominate, (b) In strong magnetic fields, tight cyclotron orbits enhance orbital ...

The Earth's magnetic field and oxygen evolved together over 540 million years, according to a major NASA study.

For decades, scientists have been trying to understand why some rocks on the moon are strongly magnetized even though the moon has no magnetic field today. "The majority of the strong magnetic fields ...
