During a brief but dramatic chapter in Earth's history about 41,000 years ago, the planet’s magnetic field nearly collapsed. What followed was a cascade of environmental and biological changes that ...
The Earth's liquid molten outer core, composed mostly of iron and nickel, exerts an electromagnetic field extending from the north and south pole that protects the planet from harmful solar particle ...
A giant dent in Earth's magnetic field is continuing to expand, according to the latest data from a trio of satellites monitoring our world. It's called the South Atlantic Anomaly, stretching across ...

Earth’s magnetic field has long been framed as a planetary force field, a protective bubble that keeps the worst of the Sun’s radiation at bay. Increasingly, though, scientists are finding that this ...
Long before life thrived in Earth’s oceans, the planet’s magnetic field became disorganized. Deep within the ancient rocks of Morocco, scientists have recovered one of the clearest records of that ...
The Earth's magnetic field quietly supports life on the planet and now, for the first time, its invisible powers have been used to create new nanoparticles and materials. Scientists at Flinders ...
Earth’s Ediacaran Period, which lasted from about 630 to 540 million years ago, has long puzzled scientists studying the ...
A small but evolving dent in Earth’s magnetic field can cause big headaches for satellites. Earth’s magnetic field acts like a protective shield around the planet, repelling and trapping charged ...
Geophysicists from ETH Zurich and SUSTech, China, have demonstrated the dynamo effect of the Earth’s core in a model in which viscosity has no influence, as is the correct physical regime for the ...
As Earth warms, much of the extra heat is stored in the planet’s ocean — but monitoring the magnitude of that heat content is a difficult task. A surprising feature of the tides could help, however.
