Mosaic of Venus' Surface

In this photo released by the European Space Agency on Wednesday, Nov. 28, 2007, the mosaic of the Venusian surface, obtained thanks to radar images from NASA's Magellan spacecraft, is seen. Nearby planet Venus is looking a bit more Earth-like with frequent bursts of lightning confirmed by a new European space probe. For nearly three decades, astronomers have said Venus probably had lightning, ever since a 1978 NASA probe showed signs of electrical activity in its atmosphere. But experts were not sure because of signal interference. Gaps in the Magellan data were filled in with Pioneer and Venera data. (AP Photo/ESA/NASA/HO)
