The region of space dominated by Earth's magnetic field is the magnetosphere. Observations have shown that, within this ...

A puzzling form of superconductivity that arises only under strong magnetic fields has been mapped and explained by a ...

For 540 million years, Earth’s magnetic field and atmospheric oxygen levels have danced in sync — and NASA scientists just ...

The Northern Lights may be visible in U.S. states after space weather experts at NOAA forecast a geomagnetic storm.

Magnetic fields play an important—if sometimes underappreciated—part in planetary systems. Without a strong magnetic field, planets can end up as a barren wasteland like Mars, or they could ...

A man died last week after being pulled into an MRI machine by a “large metallic chain” police said he was wearing around his ...

The Earth’s magnetic field, an invisible force generated by our planet’s core, serves as a natural compass that has guided human navigation for centuries. However, long before humans invented ...

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

NASA researchers have discovered a link between Earth’s magnetic field changes and atmospheric oxygen fluctuations dating back 540 million years.

The strength of Earth's magnetic field has correlated with fluctuations in atmospheric oxygen for hundreds of millions of years, according to a newly released analysis by NASA scientists ...

Earth's magnetic field and oxygen levels have increased more or less in parallel over the past 540 million years, suggesting the two factors are linked in some way, researchers say.
