The Long Range Reconnaissance Imager (LORRI) on New Horizons captured another dramatic picture of Jupiter’s moon Io and its volcanic plumes, 19 hours after the spacecraft’s closest approach to Jupiter on February 28, 2007. Io’s dayside is deliberately overexposed to bring out faint details in the plumes and on the moon’s night side. The continuing eruption of the volcano Tvashtar, at the 1 o’clock position, produces an enormous plume roughly 330 kilometers high, which is illuminated both by sunlight and „Jupiter light“.
