New Horizons casts an eye on Io, catching the north pole volcano Tvashtar kicking it up a notch. Note the other two plumes, one on the equator at left (Prometheus), and another (Masubi) manifesting as that bright patch just past the day-night terminator.
More images have been stored aboard the spacecraft and will be downloaded to Earth in the months ahead. The closest Jupiter encounter was a week ago today. Next stop is Pluto, but not for another eight years.
