月偏食

A Partial Lunar Eclipse

Explanation: What’s happened to the Moon? Within the last day, part of the Moon moved through the Earth’s shadow. This happens about once or twice a year, but not every month since the Moon’s orbit around the Earth is slightly tilted. Pictured here, the face of a full Hunter’s Moon is shown twice from Italy during this partial lunar eclipse. On the left, most of the Moon appears overexposed except for the eclipsed bottom right, which shows some familiar lunar surface details. In contrast, on the right, most of the (same) Moon appears normally exposed, with the exception of the bottom right, which now appears dark. All lunar eclipses are visible from the half of the Earth facing the Moon at the time of the eclipse, but this eclipse was visible specifically from Europe, Africa, Asia, and Australia, clouds permitting. In April, a total solar eclipse will be visible from North America.

说明: 月亮发生了什么事？在昨天，部分的月亮进到地球的影子里。这种情况大约每年会发生一到两次，不过因为月球绕地球的轨道略微侧倾，所以并不是每个月都会出现。上图为在这次月偏食期间，摄于意大利的二幅猎月之面貌。在左图里，大部分的月面过度曝光，唯有右下角的月表带着熟悉的细节。而同一月面作为对比的右图，除了看起来格外黝黑的右下角之外，大部分的月亮看来正常曝光。当月食发生时，在地球面向月球的半面，都可以看到月食；如果没受到云层遮挡的话，此例月食可见的区域分别是欧洲、非洲、亚洲和澳洲。在明年4月，北美洲可以看到日全食。
