Japanese researchers say they are closing in on the mystery of Earth’s “missing” geomagnetic polarity reversals, identifying where they believe scientists should look for evidence of their unusual ...

Earth’s magnetic field, the invisible barrier that deflects solar radiation and makes surface life possible, is not permanent in its current orientation. Geologic records show that magnetic north and ...

Several studies have predicted that not all geomagnetic reversals have been discovered, but it was unknown in which periods they might be hidden. Researchers led by the National Institute of Polar ...

Evidence suggests that the planet may be in the opening strains of a geomagnetic chicken dance, the likes of which we haven't seen for almost a million years. Share on Facebook (opens in a new window) ...

Solar physicists and seismologists are testing a provocative idea: that violent outbursts from the Sun could be linked to the timing of some large earthquakes. New statistical work reports ...
