The visualization above shows the magnetic field around Earth—the magnetosphere—as it might look from space. This view is conceptual, but based on real science observations that have been made since the beginning of the Space Age. The orange and blue lines depict the opposite north and south polarity of Earth's field lines. The field lines are not actually visible, but they can be detected by sensors that count atomic particles—protons and electrons moving in the space around Earth.
