BREAKING NOW! A special thank you to Michael Wat for this BN Headline! --- WOW!!! Earths magnetic field, which protects the planet from huge blasts of deadly solar radiation, has been weakening over the past six months, according to data collected by a European Space Agency (ESA) satellite array called Swarm. Researchers think power grids and communication systems would be most at risk. Earths magnetic field acts like a giant invisible bubble that shields the planet from the dangerous cosmic radiation spewing from the sun in the form of solar winds. The field exists because Earth has a giant ball of iron at its core surrounded by an outer layer of molten metal. Changes in the cores temperature and Earths rotation boil and swirl the liquid metal around in the outer core, creating magnetic field lines.
