Is Earth's Magnetic Field Ready to Flip? - Universe Today
Illustration of the invisible magnetic field lines generated by the Earth. Unlike a classic bar magnet, the matter governing Earth's magnetic field moves around. The flow of liquid iron in Earth's core creates electric currents, which in turn creates the magnetic field. Credit and copyright: Peter Reid, University of Edinburgh
New Study Shows How Rapidly Earth's Magnetic Field Is Changing
New research has shown in the most detail yet how rapidly Earth's magnetic field - which acts like a shield to protect us from harsh solar winds and cosmic radiation - is changing, getting weaker over some parts of the world, and strengthening over...
Protective Magnetic Fields Increase the Chance for Life on Earth-Like Planets
A new study from the the University of Washington details how Earth-like planets orbiting close to small stars may have magnetic fields that protect them from stellar radiation and help maintain surface conditions that could be conducive to life. A planet’s magnetic field emanates from its co
'Magnetic' Discovery May Reveal Why Earth Supports Life and Mars Doesn't
Earth's magnetic field, which protects the planet from harmful blasts of solar radiation, is much older than scientists had previously thought. This invisible, protective shield likely existed shortly after the planet formed; a finding that could shed light on why Earth is habitable and Mars is not. Earth's magnetic field helped make life on the planet possible. Without our magnetic field, solar winds would strip away the planet's atmosphere and oceans.
