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 ...
Our geomagnetic field is one of the things that is different about Earth as opposed to say, Venus or Mars. It acts as a ...
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 ...
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 ...
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 team of archaeologists affiliated with multiple institutions in Spain has used a new dating technique to more accurately estimate time differences between Paleolithic Age hearth fires.
The sun's magnetic field, which causes solar storms like the one that hit Earth this month and produced beautiful auroras, may originate at shallower depths in the star's interior than previously ...
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 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 ...
