Explanation: Why is a thin crescent moon never seen far from a horizon? Because the only geometry that gives a thin crescent lunar phase occurs when the Moon appears close to the Sun in the sky. The crescent is not caused by the shadow of the Earth, but by seeing only a small part of the Moon directly illuminated by the Sun. Moreover, the thickest part of the crescent always occurs in the direction of the Sun. In the evening, a thin crescent Moon will set shortly after the Sun and not be seen for the rest of the night. Alternatively, in the morning, a crescent Moon will rise shortly before the Sun after not being seen for most of the night. Pictured two weeks ago, a crescent moon was captured near the horizon, just before sunrise, far behind remnants of the ancient Temple of Poseidon in Greece.

Athens Plauge about 450 BC they figured out that natural immunity was The best way.
Of course Sparta was aided by This and
Greece was never the same.

I never can figure out or remember how to tell
a waxing moon from a waning moon just by looking at it.

Unusual, probably a first for GGG, but that's a nice shot!

Greek Mythology ping! A bow, hunting hounds, a huntress, and the moon!

The way I remember is the word "waning" means getting smaller so that's the crescent in the morning sky that gets smaller and smaller day by day as it approaches the sun.
