为什么天空中会有一只巨大的眼睛？钻石灰尘。这是一个非正式的术语，指的是在空气中形成并飘散到地面的小冰晶。由于这些晶体呈几何形状，它们可以将来自太阳或月亮的光线系统地反射到你的眼睛中，从而产生巨大的光晕和不寻常的弧线。有时，两者合在一起的结果就像一只大眼正盯着你。上周在捷克共和国的矿石山脉拍摄的特色照片中，明亮的月亮从充满冰雾的空气中升起，导致许多壮观的天空幻象同时可见。除了月亮狗、切线弧、光晕和星形圆外，在最左边可以看到远处的光柱，而木星和火星就在22度光晕的底部。你的天空惊喜：APOD在你的生日上展示了什么照片？(1995后)

Why is there a huge eye in the sky? Diamond dust. That is an informal term for small ice crystals that form in the air and flitter to the ground. Because these crystals are geometrically shaped, they can together reflect light from the Sun or Moon to your eyes in a systematic way, causing huge halos and unusual arcs to appear. And sometimes, together the result can seem like a giant eye looking right back at you. In the featured image taken in the Ore Mountains of the Czech Republic last week, a bright Moon rising through ice fog-filled air resulted in many of these magnificent sky illusions to be visible simultaneously. Besides Moon dogs, tangent arcs, halos, and a parselenic circle, light pillars above distant lights are visible on the far left, while Jupiter and Mars can be found just inside the bottom of the 22-degree halo.
