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 ...
Just over 2 billion years ago, smack-bang in the middle of the Paleoproterozoic period, Earth's magnetic field was strong. Roughly 1.5 billion years later it dropped to its lowest ebb – about 30 ...
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 ...
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 ...
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 ...
Space to play or pause, M to mute, left and right arrows to seek, up and down arrows for volume. Sally Sara: New research is examining the theory that changes in the Earth's magnetic field could ...
(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 ...
Researchers uncovered compelling evidence that Earth's magnetic field was in a highly unusual state when the macroscopic animals of the Ediacaran Period -- 635 to 541 million years ago ...
The Ediacaran Period, which lasted from 635 to 539 million years ago, was a key stage in the evolution of life on Earth.This was when complex multicellular lifeforms first emerged, but they barely ...
