Magnetic Fields

A precise record of the last major reversal of the Earth's magnetic poles can be found in ancient trees. Researchers say this event 42,000 years ago had a huge impact on the planet and ancient humans.

The Solar Orbiter, a new mission from the European Space Agency and NASA, was designed to give us our first look at the sun's poles and to gather data that might help predict space weather.

You might expect turtles that live near each other or in similar environments would be genetically similar. But new research shows that magnetic fields actually have more to do with genetic likeness.

The planet's magnetic field is weakening. Scientists aren't sure why, but studying ancient jars could help them find out. The ceramics provide a remarkable window onto Earth's magnetic past.

Space navigation is tricky. There's no up or down, no left or right, and no road signs. This device uses stars to help determine if a spacecraft is off course. It takes nifty pictures, too.
