Did you know that #Roman road design included #safety features?
In the ruins of #Pompeii, you'll notice small white stones interspersed with the large paving ones along the extensive roads.
Those white #stones are 'cats eyes', i.e. gems that have a single line of inclusion of crystals of another mineral inside.
Upon light reflective on them (from the #moon), they enable the walker to see that they are still on the right path!

Just before moonset - an infrared view of the one-day old crescent moon next to the Pleiades in the evening sky.
The moon's elevation was only about 1/2 degree above a sea level horizon. (The distant mountain range is 45 miles away, and a few thousand feet lower than the observing location. This means the mountains are at a negative elevation.)
The moon does not appear to be a circle, Instead, it's squashed flat because of atmospheric refraction.
Haze and dust layers are prominent.
Planetarium software says that I was shooting through about 30 airmasses for this image.
Taken from the mountains of southern New Mexico at an elevation of 9,000 feet.
I slightly boosted the visibility of the Pleiades stars in post processing.

Jupiter may be the reason why Earth has a moon, new study hints
The great planetary instability, which saw Jupiter and the other gas giants wander chaotically through the solar system, coincides with the collision that formed Earth's moon. Could the two events be linked?Keith Cooper (Live Science)
