This photo taken Tuesday, February 4, 2014 shows the brightly-colored newly painted fresco in the Serbian Orthodox Church of Christ's Resurrection in Montenegro's capital Podgorica. The fresco allegedly shows late Yugoslav autocratic leader Josip Broz Tito drowning in red fiery waves of hell with Karl Marx and Friedrich Engels, authors of the 1848 Communist Manifesto. They are in the company of Adam and Eve, together with some of Montenegro's current politicians and people wearing Muslim turbans. What appear to be rival church priests are being swallowed through a huge jaw of an angry gray beast with pointed devil ears. The fresco has triggered much attention and public controversy in this tiny former communist country. (Risto Bozovic/Associated Press)

This NASA handout image released February 5, 2014 shows a dramatic, fresh impact crater, captured by the High Resolution Imaging Science Experiment (HiRISE) camera on NASA's Mars Reconnaissance Orbiter on November 19, 2013. The crater spans approximately 100 feet (30 meters) in diameter and is surrounded by a large, rayed blast zone. Because the terrain where the crater formed is dusty, the fresh crater appears blue in the enhanced color of the image, due to removal of the reddish dust in that area. Debris tossed outward during the formation of the crater is called ejecta. In examining ejecta's distribution, scientists can learn more about the impact event. The explosion that excavated this crater threw ejecta as far as 9.3 miles (15 kilometers). (Photo by AFP PhotoNASA/JPL-Caltech/Univ. of Arizona)
