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 ...
Around 591 million years ago, Earth’s magnetic field almost collapsed. The near-disaster may have contributed to the ...
Researchers examined ancient plagioclase crystals to learn about Earth's history. A new study has discovered a startling record in which the Earth’s magnetic field diminished for up to 26 million ...
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 ...
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 ...
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 ...
Earth's magnetic field nearly collapsed some 590 million years ago, presumably putting life on the planet's surface at risk of a rise in cosmic radiation. "Earth's magnetic field was in a highly ...
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 ...
