Earth’s magnetic field flipped 43 million years ago — was there an impact on life?
Learn how a flip in Earth's magnetic field may have caused changes in the radiation on our planet.
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 ...

You may have seen headlines or social media posts talking about a weakening of Earth’s magnetic field, specifically over the South Atlantic. It sounds dramatic, and a little scary. Is Earth losing its ...
Recently the MagQuest competition on improving the measuring of the Earth’s magnetic field announced that the contestants in the final phase have now moved on to launching their satellites within the ...
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 ...
The solar wind flows around Earth's magnetic field. A new NASA study suggests that the amount of oxygen in the atmosphere and strength of the magnetic field have been correlated for more than half a ...
Saturn’s magnetic field isn’t the smooth, symmetrical shield scientists see around Earth. Instead, it’s noticeably skewed, ...
Saturn's magnetic shield is asymmetrical compared to Earth's, suggests a new study involving University College London (UCL) ...
