Crescent Venus and Moon
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 |
