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 supercharging evolution. A near collapse of Earth's magnetic field may ...
Researchers examined ancient plagioclase crystals to learn about Earth's history. A new study has discovered a startling record ...
Around 591 million years ago, Earth’s magnetic field almost collapsed. The near-disaster may have contributed to the ...
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 ...
The emergence and diversification of multicellular organisms on Earth appears to have coincided with the weakest magnetic field in Earth's history, which suggests a direct correlation. This has ...
Peer-reviewed: This work was reviewed and scrutinised by relevant independent experts. An unusual reduction in the strength of ...
Earth’s magnetic field protects life from harmful cosmic radiation. But sometime between about 590 million and 565 million years ago, that security blanket seems to have been much thinner ...
An ultra-weak geomagnetic field between 591 and 565 million years ago (Ediacaran period) coincided with a significant increase in ...
A new study suggests more solar radiation reached Earth while the magnetic field weakened, leading to a rise in oxygen that drove an explosion of multicellular organisms during the Ediacaran ...
