月掩金星，有国外大佬挑战成功了！

Explanation: On May 27 Venus rose as the morning star, near the waning crescent Moon in a predawn sky already full of planets. It was close on the sky to the Moon's crescent and a conjunction of the second an third brightest celestial beacons were enjoyed by skygazers around the world. But seen from locations along a track through southeast Asia and the Indian Ocean the Moon actually passed in front of Venus in a lunar occultation. In this animated gif the 75 percent illuminated disk of Venus approaches and just begins to disappear behind the sunlit southwestern lunar limb. The telescopic frames used to construct it were captured from Reunion Island in the Indian Ocean around 4:50am local time, with the Moon and Venus very close to the eastern horizon. At the time Venus was over 180 million kilometers from Reunion Island, compared to a lunar distance of a mere 400 thousand kilometers or so. About 50 minutes later Venus emerged from behind the Moon.

5月27日，金星作为晨星升起，在黎明前已经布满行星的天空中，它在天空中靠近明亮的的新月，世界各地的天文观测者都欣赏到了第二和第三亮的天球。但从穿过东南亚和印度洋的轨道上看，月球实际上是在月球掩星中从金星前面经过的。在这张动画gif中，75%的金星圆盘接近并开始消失在阳光照射下的西南月球边缘后面。用于建造它的望远镜框架是在当地时间凌晨4:50左右从印度洋留尼汪岛拍摄的，当时月亮和金星非常接近东方地平线。当时金星距离留尼汪岛超过1.8亿公里，而月球距离只有40万公里左右。大约50分钟后，金星从月球后面出现。（BySASU北斗星辰）
