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 ...
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 ...
Add Yahoo as a preferred source to see more of our stories on Google. The Earth's magnetic field deflects particles emitted by the Sun. Mark Garlick/Science Photo Library via Getty Images The Earth’s ...
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 ...

NASA discovers hidden dynamo in space that powers Earth’s magnetic field
NASA’s Magnetospheric MultiScale (MMS) mission has uncovered a phenomenon previously unseen in space. Scientists have ...
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 ...
Hundreds of millions of years ago, Earth’s magnetic field behaved in a way that has long baffled scientists, showing wild and ...

It’s official: Earth’s magnetic north pole shifted again, and it’s moving into unmapped magnetic territory
Earth’s magnetic north pole has a new official position. The updated World Magnetic Model 2025, released by the National ...
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 ...
High-energy particles called galactic cosmic rays (GCRs) bombard unprotected objects in space, often causing damage. Earth, however, is protected by its magnetic field, which creates a protective ...
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.
