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 ...
Our geomagnetic field is one of the things that is different about Earth as opposed to say, Venus or Mars. It acts as a ...
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 ...
Today, Earth’s magnetic field acts as a safety blanket, shielding the planet from dangerous solar wind. Without the protection of our magnetosphere, you, me and almost every other living thing ...
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 ...
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 ...
