Did you know… this is the Earth’s magnetic field becoming visible? Did you know – this magnetic field is what keeps our atmosphere protected against solar radiation that would blow away the atmosphere and the water into space? (as it did with 85% of the water on #Mars!) Mars lost it’s magnetic field when it’s iron core stopped spinning around 4 billion years ago. i am glad we still have our iron core spinning.
