The HiRISE camera aboard NASA’s Mars Reconnaissance Orbiter (MRO) is specifically designed to take super high-resolution images of the surface of Mars but it also does a pretty darn good job capturing pictures of other objects too—like Jupiter and its Galilean moons, several hundred million miles away! The image above was captured in extended color (i.e. it includes wavelengths in near-infrared) by HiRISE on January 11, 2007, and shows the giant planet from Mars orbit.
Mars and Jupiter were at opposition at the time, only about 345 million miles apart.
The image has been sharpened from its original version by Dennis Gallagher, the HiRISE chief optical designer, using processing software since HiRISE wasn’t actually set up to make the observation when it occurred.
(I also added some black space around it for better framing—you can see the original released version here.)
With the sharpening, HiRISE achieved a similar resolution to the Hubble Space Telescope.

Launched on Aug. 12, 2005, MRO with HiRISE arrived at Mars on March 10, 2006.
