Then, in 1973, two geophysicists called Christopher Russell and Robert McPherron presented a theory involving the magnetic fields of the Earth and the Sun. Most of the time, the Earth and Sun’s ...

A new study reports that researchers have successfully used a meticulously designed cylinder to harness electricity as it passed through Earth’s magnetic field. However, some experts are ...

A weak magnetic field likely attracted matter inward, contributing to the formation of the outer planetary bodies, from ...

This, in turn, affects convection in the outer core—the dynamo-like process that generates the magnetic field that protects life on Earth from harmful cosmic rays. "Flow in the outer core drives ...

Now, though, a controversial new paper warns that falling space junk could actually weaken Earth’s magnetic field. If that happens, the author of the paper argues that we could see atmospheric ...
