Moon Occults Venus

Explanation: It may look like Earthrise, but it’s actually Venus-set. Just after sunrise two days ago, both the Moon and Venus also rose. But then the Moon overtook Venus. In the featured image sequence centered on the Moon, Venus is shown increasingly angularly close to the Moon. In the famous Earthrise image taken just over 50 years ago, the Earth was captured rising over the edge of the Moon, as seen from the Apollo 8 crew orbiting the Moon. This similar Venus-set image was taken from Earth, of course, specifically Estonia. Venus shows only a thin crescent because last week it passed nearly in front of the Sun, as seen from Earth. The Moon shows only a thin crescent because it will soon be passing directly in front of the Sun, as seen from Earth. Today, in fact, two days after this image was taken, the Moon will create a solar eclipse, with a thin swath across the Earth treated to an annular solar eclipse.

说明：这幅影像乍看像是地出景观，其实它记录了金星落。在2天前的日落之后，月亮与金星同时升起，不过后来月亮掩过金星。在这幅以月亮为主角的时序主题影像里，金星在张角上越来越靠近月亮。50多年前的那幅著名的地出影像，是以当时绕行月亮的阿波罗八号组员之视点，记录了地球从月缘升起的景观。这张类似的金星落影像，则是摄于地球的爱沙尼亚共和国。其中的月亮带着纤细的蛾眉相，因为在上星星拍照时，从地球看出去，它很快的即将通过太阳的前方。在拍下这幅影像的2天之后的今天，月亮将造成一次日食，在地表一道狭窄的食带内得以见到日环食。
