There is a region of our planet that no human being has ever visited, no one has ever seen this place, yet what happens here effects everyone of us every day of our lives. Its 2000 miles beneath our feet, the earths molten core. Here a vast ocean of liquid iron generates an invisible forcefield, the earths magnetic field. It surrounds our entire planet cocooning us from the dangers of space, but now scientists have made an alarming discover, there is a storm brewing deep within the earth, a storm which could destroy our vital magnetic field.
