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.
Generated by the molten iron core of Earth, the magnetic field is essential for life on Earth, protecting against radiation ...
Earth’s magnetic field was once 30 times weaker than it is today. This change may have played a pivotal role in the blossoming of complex life, new research found.
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 ...
However, Earth’s magnetic field almost collapsed 591 million years ago, and this change, paradoxically, may have played a pivotal role in the blossoming of complex life, new research has found ...
(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 ...
