Mars Rises above the Lunar Limb

Explanation: On the night of December 7 Mars wandered near the Full Moon. In fact the Red Planet was occulted, passing behind the Moon, when viewed from locations across Europe and North America. About an hour after disappearing behind the lunar disk Mars reappears in this stack of sharp video frames captured from San Diego, planet Earth. With the Moon in the foreground Mars was a mere 82 million kilometers distant, near its own opposition. Full Moon and full Mars were bright enough provide the spectacular image with no exposure adjustments necessary. In the image Mars appears to rise just over ancient, dark-floored, lunar crater Abel very close to the southeastern edge of the Moon’s near side. Humboldt is the large impact crater to its north (left).

说明: 在12月7日那晚，火星晃荡到满月附近。而从欧洲和北美的诸多地点看出去，这颗红色行星通过月亮的后方，带来月掩火星的景观。火星消失在月盘后方约1小时之后，如这幅摄于地球·圣地亚哥的清晰视频定格所示，复现于月盘的边缘。在这片以月亮为前景的视野里，位在火星冲位置附近的红色行星，距离我们只有8200万公里。由于满相的月亮和火星都够明亮，故不需调整曝光设定即可取得很精采的图像。在图像里，火星看似从月亮正面东南缘附近的古老、黝黑阿贝尔坑（crater Abel）的后方升起。洪堡坑（crater Humboldt）则是其北方（左）的大撞击坑。
