Tablizer writes: The New Horizons probe caught the moon Io in the act of barfing into space. "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...The appearance and motion of the plume is remarkably similar to an ornamental fountain on Earth, replicated on a gigantic scale."
