Jupiter and its volcanic moon
New Horizons performed a flyby of Jupiter as it made its way towards the outer solar system. The encounter provided a gravitational assist, but it also served as a kind of dress rehearsal for Pluto, and it resulted in more scientific data than scientists had anticipated. Among the many images the craft acquired was a stunning montage showing Jupiter and its volcanic moon Io. The shot of Jupiter, shown in an infrared color composite, was taken on February 28, 2007, while the shot of Io, shown in true-color, was taken on March 1, 2007.
