Earth’s powerful magnetic field shields life on the planet from the severe cosmic radiation as we know it. This is what sets our blue world apart from Venus and Mars. However, the Earth’s ...
The planet's magnetic field may have collapsed around 600 million years ago, enabling a major oxygenation event and perhaps ...
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 ...
Around 591 million years ago, Earth’s magnetic field almost collapsed. The near-disaster may have contributed to the ...
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.
(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 ...
