WebIn addition to bow shocks produced by planets like Earth and Jupiter, astronomers have observed shocks from fast-moving stars plowing through interstellar gas, and shock waves from colliding galaxy clusters. On a smaller scale, shock waves driven by solar storms can endanger satellites and astronauts. Web2.1 Earth’s Bow Shock. The paradigm of a planetary bow shock embedded into a super-magnetosonic stellar wind flow is the Earth’s bow shock wave. Its continuous …

Bow shocks form at comets as a result of the interaction between the solar wind and the cometary ionosphere. Far away from the Sun, a comet is an icy boulder without an atmosphere. As it approaches the Sun, the heat of the sunlight causes gas to be released from the cometary nucleus, creating an atmosphere called a coma. The coma is partially ionized by the sunlight, and when the solar wind passes through this ion coma, the bow shock appears. WebJul 28, 2013 · What is the bow shock or bow wave?
