Explanation: Can you find the Sun? OK, but can you explain why there’s a big dark spot in the center? The spot is the Moon, and the impressive alignment shown, where the Moon lines up inside the Sun, is called an annular solar eclipse. Such an eclipse occurred just last week and was visible from a thin swath mostly in Earth‘s southern hemisphere. The featured image was captured from Patagonia, Chile. When the Moon is significantly closer to the Earth and it aligns with the Sun, a total solar eclipse is then visible from parts of the Earth. Annular eclipses are slightly more common than total eclipses, but as the Moon moves slowly away from the Earth, before a billion more years, the Moon’s orbit will no longer bring it close enough for a total solar eclipse to be seen from anywhere on Earth.

说明: 你找得到太阳吗？很好！不过，你能解释为何它的中心有个大黑斑吗？这个黑斑是月亮，而影像所呈现的、月亮镶在太阳之内的天体对齐景观，则称为日环食。这例发生在上星期的日环食，基本上只有在地球南半球的一道狭窄食带内才得见。例如这幅主题影像，即是摄于智利的巴塔哥尼亚。当月亮掩食太阳时，如果月亮很接近地球，地球上的部分区域可看到日全食。日环食要比日全食稍微常见一些；然而，随着月亮逐渐离地球远去，未来再过不到10亿年，月亮的轨道已离地球颇远，届时地球上的任何地方都再也看不到日全食。
