        Solar Magnetism

        The Sun — Earth's main source of energy — appears to shine at a constant rate. However, the Sun's magnetic field is actually constantly changing, and this affects its energy output. These variations cause effects that extend throughout the solar system. In this video segment adapted from NOVA, learn about some of the effects that solar activity may have on Earth.
