A Daylight Eclipse of Venus

Explanation: Something was about to happen. Just two days ago, two of the three celestial objects easily visible during the day appeared to collide. But actually, Earth's Moon passed well in front of the distant planet Venus. The occultation was caught from Switzerland in the hours before sunset. Moments after this image was taken, the Moon, visible as the crescent on the right of the above image, eclipsed Venus, appearing in gibbous phase on the lower left. Clouds that once threatened to obscure the whole event, were visible on the far left. About 90 minutes later, Venus re-appeared just to the right of the bright crescent.

解释: 有些事要发生了.仅仅两天前,三个天体中的两个很容易的在白天里看到好像要相撞的样子.但实际上月球很好地在遥远的行星金星前通过.这一掩食现象是在日落前一小时拍于瑞士.在拍了这张照片的一会儿后,上图右面的新月掩食了左下呈现出凸月形的金星,曾要遮掩这个掩食过程的云,可以在左方的远处看到.90分钟后,金星再次出现在明亮的新月右边.
