Planetary Aurora across the Solar System

One of the most recognizable examples of magnetosphere-ionosphere coupling is bright auroral emissions produced by charged particle excitation of a planetary atmosphere. Although the canonical example has long been Earth, auroral emissions are pervasive across the solar system, not only on other planets (Jupiter, Saturn, Uranus, Neptune, and perhaps Mercury), but also on planetary satellites (most notably the Galilean satellites of Jupiter: Io, Europa, Ganymede, and Callisto). This talk will give a brief overview of auroral emissions seen on planets and satellites other than Earth, with an emphasis on comparison and contrast of the magnetosphere-ionosphere interactions that produce the auroral emissions
