Impact craters can be tough to detect from the ground, especially if they are situated in remote locations and covered by vegetation. Both factors hampered understanding of the Luizi Structure, located in southeastern Congo. The crater is covered by grasses up to a meter (3 feet) high, and tucked away in central Africa. The Advanced Land Imager (ALI) on NASA’s Earth Observing-1 (EO-1) satellite captured this natural-color image of Luizi on June 2, 2012. It is not perfectly round, but instead fills a semicircular basin where vegetation carpets the complicated topography. A mention of Luizi made it into a geological report in 1919, but the feature remained unexplored for decades. Satellite imagery of the structure from the 1990s inspired an international team of geologists to look more closely. In 2011, they announced their findings. Satellite imagery suggested that Luizi mi...
