Major eruption in volcanic Moon Io

Jupiter's moon Io

This NASA montage of New Horizons images shows Jupiter and its volcanic moon Io, taken during the spacecraft’s Jupiter flyby in early 2007. The image shows a major eruption in progress on Io’s night side, at the northern volcano Tvashtar. Incandescent lava glows red beneath a volcanic plume, whose uppermost portions are illuminated by sunlight. The plume appears blue due to scattering of light by small particles within it.
