This map of Europa employs 190 images from NASA's Galileo spacecraft and 14 images from NASA's Voyager 2 spacecraft that have been color-matched to produce as seamless a global map as practicable with current data sets. Warning: the fully enlarged version is 20,000 by 10,000 pixels and about 30 Megabytes; some browsers may not display it.

One of the more intriguing aspects of Vesta as seen by Dawn is the "dark material" found across its surface. In most places, dark material is associated with craters. In this photo, the dark material shows up in the ejecta around two large impact craters, but the relationship between the dark stuff and the crater is not obvious. The left crater is the 17-kilometer-diameter Fulvia. In some places the dark material seems to be associated with small secondary craters, but in other places there is no obvious origin. This photo consists of three high-resolution images taken on December 20, 2011, March 13, 2012 and April 17, 2012, colorized with a lower-resolution image taken on September 30, 2011.
