APOD: The Old Moon in the Young Moon's Arms (2018 Nov 10)

Image The Old Moon in the Young Moon's Arms

Explanation: Tonight the Moon is young again, but this stunning image of a young Moon near the western horizon was taken just after sunset on October 10. On the lunar disk Earthshine, earthlight reflected from the Moon's night side, is embraced by the slim, sunlit crescent just over 2 days old. Along the horizon fading colors of twilight silhouette the radio telescope dish antennas of the Very Large Array, New Mexico, planet Earth. The view from the Moon would be stunning, too. When the Moon appears in Earth's sky as a slender crescent, a dazzlingly bright, nearly full Earth would be seen from the lunar surface. A description of earthshine, in terms of sunlight reflected by Earth's oceans in turn illuminating the Moon's dark surface, was written 500 years ago by Leonardo da Vinci.

Leonardo's vivid imagination of standing upon the moon looking at the earth was also accomplished by Dante Alighieri in his Paradiso nearly two centuries prior. Thus Leonardo was building upon a tradition of poetic artistic scientific imagination.

<<When visiting the Moon, Beatrice explains to Dante the reasons for the markings on its surface, describing a simple scientific experiment in optics. She also praises the experimental method in general (Canto II):
  • Yet an experiment, were you to try it,
    could free you from your cavil, and the source
    of your arts' course springs from experiment.
The waxing and waning of the moon is associated with inconstancy. Consequently, the sphere of the Moon is that of souls who abandoned their vows, and so were deficient in the virtue of fortitude (Canto II).>>
