Greek skywatcher Emmanuel Kardasis of the Hellenic Amateur Astronomy Association created the new Ganymede map using a common "hobby" telescope and off-the-shelf camera and computer equipment. His map matches up well with images of Ganymede's surface taken by professionals, said officials with the European Planetary Science Congress (EPSC), which is meeting this week in Madrid. For example, Kardasis' brightness (or albedo) map identifies such Ganymede features as Phrygia Sulcus, a system of grooves and ridges thousands of miles across, and a low-lying dark area called the Nicholson region. To create the images, Kardasis attached a camera to his telescope and recorded a video of the ice-covered Ganymede, which is the largest moon in the solar system at 3,273 miles (5,268 kilometers) across. He picked the video's sharpest frames, then enhanced them using photo-editing software, EPSC officials said.

Never attribute to malice that which is adequately explained by stupidity.
