Something I learned today: maps and chart are absolutely great instruments to share data, with a good map you can show complex data and allow people to understand them. But we need that maps/charts to be based on reliable data, because if a good map could help complex data to be share easily, a map based on partial/incaccurate/misleading data can bring only misinformation.
This is why we need to know the sources to trust something.

Recent Earthquakes near Japan
This web map shows recent earthquakes off the coast of Japan. The web map features a live map service from the USGS Earthquake Hazards Program displayed over pre-earthquake imagery of the area.
This sheet is one in a series of maps of the Galilean satellites of Jupiter at a nominal scale of 1:15,000,000. This series is based on data from the Galileo Orbiter Solid-State Imaging (SSI) camera and the Voyager 1 and 2 spacecraft. (via USGS Astrogeology)
Mars: Map with the names of large regions
This is a color-coded shaded relief map of the Martian surface with major regions labeled on the map. The shadows and highlights of the shaded relief (similar to the shaded relief of the Moon to the left) gives the map a sense of texture. The colors differentiate the elevation — violet and blue being low elevations, tan and white being high elevations. The map base was created using data from the Mars Orbiter Laser Altimeter.
