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 ...
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 ...
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 ...
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 ...
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 ...
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 ...
(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 swings in ...

Our Observatory, along with several others around the world, is involved in a project called GMIMS (pronounced “Gee Mims). This stands for “Global Magneto-Ionic Medium Survey.” As in many projects, a ...
