Earth's magnetic field shields us from deadly cosmic radiation, and without it, life as we know it could not exist here. The motion of liquid iron in the planet's outer core, a phenomenon called a "geodynamo," generates the ...

(Phys.org)—Like the solar system's telluric planets, including Earth itself, the moon's internal structure is composed of geoochemically distinct mantle, crust and core layers. The core is mostly iron; much of our understanding ...
(Phys.org) —A trio of planetary scientists from France, Switzerland and the U.K. has used seismic data, lab experiment results and theoretical calculations as a means to offer proof that oxygen is present in the Earth's ...
(Phys.org) —A trio of researchers from France and Denmark has combined data obtained over the past several centuries to create a model depicting the westward drift of the Earth's magnetic field. In so doing as they explain ...
Scientists at the University of Leeds have solved a 300-year-old riddle about which direction the centre of the earth spins.
