The Parker Spiral is a model that describes the structure of the interplanetary magnetic field as it extends from the Sun into the heliosphere, taking the shape of a spiral due to the solar wind. This spiral pattern results from the combination of the Sun's rotation and the outward flow of solar plasma, influencing the magnetic field lines in a way that affects space weather and cosmic ray propagation throughout the solar system.
congrats on reading the definition of Parker Spiral. now let's actually learn it.
