My discussion moved from our position in the galaxy, our position in the solar system, and then focused on the earth, looking at the influence of our moon, our […]
By capturing solar 'sneezes' of high-energy charged particles, the Van Allen Belts provide a prime example of how the earth and its space environment are designed to allow and protect life.
