July 8, 2008 -- Picture shows montage of New Horizons images of Jupiter and its volcanic moon Io, taken during the New Horizons’ Jupiter flyby on Feb. 28, 2007. The prominent bluish-white oval is the Great Red Spot. The Io image shows a major eruption in progress on Io’s night side, at the northern volcano Tvashtar.
