The weakened magnetic field may have led to increased oxygen concentrations in our atmosphere and oceans, triggering an ...
The planet's magnetic field may have collapsed around 600 million years ago, enabling a major oxygenation event and perhaps ...
A new study suggests more solar radiation reached Earth while the magnetic field weakened, leading to a rise in oxygen that ...
Decreased protection from cosmic radiation may have increased oxygen levels in the atmosphere and oceans, allowing animals to grow larger.
Just over 2 billion years ago, smack-bang in the middle of the Paleoproterozoic period, Earth's magnetic field was strong. Roughly 1.5 billion years later it dropped to its lowest ebb – about 30 ...
Generated by the molten iron core of Earth, the magnetic field is essential for life on Earth, protecting against radiation ...
You may not know this, but Earth's magnetic field has a tail. As the sun 's solar wind buffets the planet, it leaves behind a ...
A study suggests Earth's weakest magnetic field 591-565 million years ago could have increased oxygen, aiding early life diversification.
(CNN) — Earth’s magnetic field plays a key role in making our planet habitable. The protective bubble over the atmosphere shields the planet from solar radiation, winds, cosmic rays and wild ...
Imagine taking a significant amount of metals and other materials out of the Earth’s crust and scattering it into the atmosphere from space. This is effectively what we have been doing ever ...
We’re used to Hall effect devices as proximity sensors in mechanical systems, used to provide detection of something that has a magnet attached to it. However it’s easy to forget that the ...
