Secret Worlds: The Universe Within
View the Milky Way at 10 million light years from the Earth. Then move through space towards the Earth in successive orders of magnitude until you reach a tall oak tree just outside the buildings of the National High Magnetic Field Laboratory in Tallahassee, Florida. After that, begin to move from the actual size of a leaf into a microscopic world that reveals leaf cell walls, the cell nucleus, chromatin, DNA and finally, into the subatomic universe of electrons and protons

What Shields The Earth?
The Earth's space storm shield is a tenuous layer of the outer atmosphere (outer ionosphere) between 180-620 miles (300-1,000 kilometers) high that includes electrically charged atoms. "Just as a heat shield sacrifices itself by allowing its outer layers to slough off during the fiery reentry of a spacecraft, Earth's shield absorbs space storm energy by throwing some of its charged particles into space," said Stephen Fuselier of the Lockheed-Martin Advanced Technology Center, Palo Alto, Calif., who is lead author of the first of two papers on this discovery to be published in the Journal of Geophysical Research.
