This is NASA’s Astronomy Picture of the Day for April 30th. It’s a nighttime photo of the Cerro de la Bufa, a distinctive rock formation standing above the city of Zacatecas. (Click here for a daytime photo).
Look at the nighttime sky above the Bufa, and notice that the crescent moon and the planets of Venus and Saturn form a somewhat-sideways smiley face. It’s impressive!
