The Moon thought to play a major role in maintaining Earth's magnetic field
Paris, France (SPX) Apr 01, 2016
The Earth's magnetic field permanently protects us from the charged particles and radiation that originate in the Sun. This shield is produced by the geodynamo, the rapid motion of huge quantities of liquid iron alloy in the Earth's outer core. To maintain this magnetic field until the present day, the classical model required the Earth's core to have cooled by around 3,000C over the past 4.3 billion years. Now, a team of researchers from CNRS and Universite Blaise Pascal1 suggests that, on the co ... read more
