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 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 ...
(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 ...
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 swings in ...
A near collapse of Earth's magnetic field may have paved the way for life to evolve past the microscopic stage. New research on ancient rocks from South Africa and Brazil suggests that Earth's ...
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.
