  • Early Origin of Earth's Magnetic Field Earth's magnetic field protects us from stellar winds and radiation from the Sun. Understanding when, during the Earth's formation, the large-scale magnetic field was established is important because it impacts understanding of the young Earth's atmosphere and exosphere. By analyzing ancient silicate crystals, Tarduno et al. (p. 1238; see the Perspective by Jardine) demonstrate that the Earth's magnetic field existed 3.4 to 3.45 billion years ago, pushing… CONTINUE READING
