WebFeb 19, 2013 · Bow shocks are shockwaves created when the solar wind blows on a planet's magnetic field. Under quasi-parallel conditions, the planet's magnetic field is roughly pointing toward the shock surface, almost parallel to a vector at right angles to the shock front (red arrow). WebDec 23, 2024 · As the solar winds encounter our magnetosphere the reaction is similar to a ship's bow (earth) traveling through a body of water (the solar winds) and the force of the interaction, like a bow making waves, pushes back the solar winds and forces them to pass around the edges of the head of magnetosphere. Scientist have termed this bow shock.
