APOD 1.8

http://apod.nasa.gov/apod/ap101020.html

This is a picture of Venus in the sky caught over 44 nights. The hilarious writers over at NASA tell us that the difference between Venus and an airplane is that an airplane will move in a few moments. From the first link I learned the totally unrelated fact that white holes exist, but not physically, only as mathematical constructs when you remove the star that created the black hole in the first place. Venus shifts its position each night, making it a bit more difficult to track. This picture was taken in Turkey. Venus is colloquially called 'the evening star' when it appears in the west. The ancient Greeks called it Hesperus. This month mars also appears near the horizon.
