A massive and evolving weak spot in Earth’s magnetic field, known as the South Atlantic Anomaly (SAA), has caught the ...

NASA has been monitoring a strange anomaly in Earth's magnetic field: a giant region of lower magnetic intensity in the skies above the planet, stretching out between South America and southwest ...

Scientists have captured faint magnetic signatures resulting from the tidal movement of seawater across the planet — and they might have to wait until 2030 to get another shot at it.

As sunspots emerge on the sun's surface close to its equator, their orientations will match the old magnetic field, while ...

A fairly well-known phenomenon called South Atlantic Anomaly (SAA) refers to the unusually weak magnetic field over South America and the southern Atlantic Ocean. And scientists acknowledge that ...

When some of the biggest stars reach the end of their lives, they explode in spectacular supernovas and leave behind ...

Swarm satellites detect faint ocean magnetic signals, revealing magma distribution and climate change insights.

Your navigation system just got a critical update, one that happens periodically because Earth’s magnetic north pole keeps moving. Here’s what to know.

A study using data from ESA's Swarm mission suggests that faint magnetic signatures created by Earth's tides can help us ...

Earth’s magnetic north is not static. Like an anchorless buoy pushed by ocean waves, the magnetic field is constantly on the move as liquid iron sloshes around in the planet’s outer core.
