月掩金星，有國(guó)外大佬挑戰(zhàn)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，金星作為晨星升起，在黎明前已經(jīng)布滿行星的天空中，它在天空中靠近明亮的的新月，世界各地的天文觀測(cè)者都欣賞到了第二和第三亮的天球。但從穿過(guò)東南亞和印度洋的軌道上看，月球?qū)嶋H上是在月球掩星中從金星前面經(jīng)過(guò)的。在這張動(dòng)畫(huà)gif中，75%的金星圓盤(pán)接近并開(kāi)始消失在陽(yáng)光照射下的西南月球邊緣后面。用于建造它的望遠(yuǎn)鏡框架是在當(dāng)?shù)貢r(shí)間凌晨4:50左右從印度洋留尼汪島拍攝的，當(dāng)時(shí)月亮和金星非常接近東方地平線。當(dāng)時(shí)金星距離留尼汪島超過(guò)1.8億公里，而月球距離只有40萬(wàn)公里左右。大約50分鐘后，金星從月球后面出現(xiàn)。（BySASU北斗星辰）
