The key to understanding Earth's prehistoric magnetic field lies hidden in the rocks. Specifically, igneous rocks, basalts that cooled from liquid magma spewed out of volcanos. Geologist Lisa Tauxe of the University of California, San Diego, and her team, traveled to Antarctica to collect rock samples that can tell them more about the planet's magnetic field over the past few million years. The research was funded by the National Science Foundation, which manages the U.S. Antarctic Program.

The Earth is constantly showered with micrometeorites, every minute of every day. These interstellar particles are no bigger than a grain of sand, but are falling out of the sky everywhere. Collecting this cosmic dust, and separating it from terrestrial contamination, has led scientists to the most remote corner of the planet.
