Earth is fortunate in having a magnetic field: it protects the planet and its life from harmful cosmic radiation. Other ...

Boldly etched into the flow of solidifying lava across Earth, the Matuyama-Brunhes event is used by geologists as a marker of ...

The magnetized rocks of Earth's crust and mantle, also known as the upper lithosphere, accounts for generating 6 percent of ...

The Earth's magnetic field is essential to life as we know it. But it’s something we can never see – or hear, until now. In a recent study released on Oct. 10 by the European Space Agency ...

The magnetic fields are more than a thousand times stronger than the magnetic field used in MRI machines. Sharon Osbourne ...

Earth's magnetic field dramatically flipped roughly 41,000 years ago. We can now experience this epic upheaval, thanks to a clever interpretation of information collected by the European Space ...

These rocks offer evidence that Earth had a strong magnetic field 3.7 billion years ago, but scientists aren't sure where that field could've come from.

An unusual reduction in the strength of Earth's magnetic field between 591 and 565 million years ago coincided with a significant increase in the oxygen levels in the atmosphere and oceans ...

Further, physicists like Cohen say that the Earth’s magnetic field isn’t going to flip overnight. This is something that reverses on a time scale between 100,000 and 1,000,000 years.

Life on Earth may exist thanks to a brief faltering in our planet's protective magnetic field shell, scientists have found. A bizarre drop in the strength of the magnetic field has been found to ...

An illustration of Earth's magnetic field, the Earth, the solar wind, the flow of particles. Research suggests the magnetic field nearly collapsed around 600 million years ago, and that may have ...
