NASA's Hubble Space Telescope made this close-up view of an electric-blue aurora that is eerily glowing one half billion miles away on the giant planet Jupiter in 2010. Jupiter’s auroras are the most powerful in the solar system. What’s puzzling is, despite the magnitudes of these potentials at Jupiter, they are observed only sometimes and are not the source of the most intense auroras, as they are on Earth. At Jupiter, the brightest auroras are caused by some turbulent acceleration process that remains poorly understood. Peter Delamere, a professor of space physics at the University of Alaska Fairbanks Geophysical Institute, is among an international team of 13 researchers who have made a fundamental discovery related to the aurora of our solar system‘s most giant planet.
