Io, Io, It’s Off to Pluto We Go!

A plume rises from a volcano over Jupiter’s moon Io in this image taken by the New Horizons spacecraft. The volcano Tvashtar is marked by the bright glow  at the moon’s edge, beyond the day/night shadow line. The shadow of Io cuts across the plume itself. The image was recorded when the spacecraft was 2.3 million km from Io during a slingshot maneuver around Jupiter which provided a boost in the New Horizons‘ velocity for the spacecraft’s encounter Pluto in 2015 and the Kuiper Belt Object Arrokoth in 2019.
