Astronomy Picture of the Day - Diamond Dust Sky Eye
NASA ^ | 25 Dec, 2024 | Image Credit & Copyright: Jaroslav Fous

Explanation: 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 parhelic 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.

I’m seeing random flat-earthers again on Truth Social posting their nonsense and that picture has me wondering if such a phenomenon is possible with a flat earth.

My step-son was about 6 years old and we saw a Sun Dog in the sky one sunny winter day, so I explained to him how that worked. At some point in the conversation I used the term, ‘Optical Illusion.’

Later I heard him telling his Dad that he knows all about ‘Obstacle Delusions,’ now.

We laughed over that one for years on end. ;)

That is so cool! I really like the labeling of the different optical effects.

It’s ONLY possible if the earf is flat!

The picture proves it.
