NASA New Horizons Image: Io’s Tvashtar Volcano Eruption – in Motion

“This five-frame sequence of New Horizons images captures the giant plume from Io’s Tvashtar volcano. Snapped by the probe’s Long Range Reconnaissance Imager (LORRI) as the spacecraft flew past Jupiter earlier this year, this first-ever “movie” of an Io plume clearly shows motion in the cloud of volcanic debris, which extends 330 kilometers (200 miles) above the moon’s surface. Only the upper part of the plume is visible from this vantage point – the plume’s source is 130 kilometers (80 miles) below the edge of Io’s disk, on the far side of the moon.”
