Some planets take the expression "you're your own worst enemy" to the extreme — triggering stellar flares from their own ...

LOFAR detects a faint radio 'mini-halo' from 3.8 billion years ago, revealing how galaxy clusters evolved in the early ...

For over half a billion years, Earth’s magnetic field has risen and fallen in sync with oxygen levels in the atmosphere, and scientists are finally uncovering why. A NASA-led study reveals a striking ...

Geologic records reveal that magnetic field strength and oxygen levels rise and fall together, implying deep-Earth processes ...

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

At its peak around 40,977 years ago, Earth’s protective magnetic bubble shrank dramatically – from its normal extent of 8-11 Earth radii (51,000-70,000 km) to just 2.43 Earth radii (15,498 km).

During a brief but dramatic chapter in Earth's history about 41,000 years ago, the planet’s magnetic field nearly collapsed. What followed was a cascade of environmental and biological changes ...

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.

The last true sustained reversal of the magnetic poles happened around 780,000 years ago – but more recently, around 41,000 years ago, Earth went through the Laschamp event.

Fluctuations in the strength of Earth's magnetic field —caused by daily changes in solar wind structure and intermittent solar storms—can impact the use of geomagnetic field models which are ...
