An aurora, a display of light in the sky, is created when energetic charged particles collide with an atmosphere. On Earth, aurorae are typically seen in the polar regions between 65 and 72 degrees north and south latitudes, although occasionally are visible as far south as New Mexico. These brilliant light shows are a dramatic display of the complex interaction between the solar wind and the Earth’s magnetic field, and are fundamental to understanding Earth’s space environment. Dr. Delamere will compare Earth’s aurora to Jupiter’s. Though surprisingly similar in form, Jupiter’s aurorae are driven by mechanisms fundamentally different from Earth’s, leaving researchers to debate exactly how they are created.
