Io eruption

26 Feb, 2007

New Horizons-Io2From 4 million km (2.5 million miles) away, New Horizons’ LORRI instrument photos Io’s Tvashtar volcano erupting. Jupiter’s tidal interaction with Io heats it up and causes it to be volcanically active. The bright photo shows Tvashtar erupting a huge dust plume at the 11 o’clock position. The bumps at the 2 o’clock position are tall mountains. The darker photo shows surface features of Io.

This is the best image of a large volcanic plume on Io since the Voyager flybys in 1979.
