Explanation:
There's something behind these clouds.
Those faint graceful arcs, upon inspection, are actually far, far in the distance.
They are the
Earth's Moon and the
planet Venus.
Both the Moon and Venus
are bright enough to be seen during the day, and both are quite capable of showing a
crescent phase.
To see Venus, which appears quite small, in a
crescent phase requires
binoculars or a telescope.
In the
above dramatic daytime image taken from
Budapest,
Hungary, the
Moon and Venus shared a similar crescent
phase a few minutes before the
Moon eclipsed the larger but more distant world.
About an hour later, Venus reappeared.
