The night sky above Cerro Tololo Inter-American Observatory at Cerro Tololo, Chile. The bright region in the centre of the photograph is the Milky Way Galaxy, while the band of white light appearing to emerge from the horizon and stretch to the Milky Way is zodiacal light, caused by sunlight reflecting off stardust (sense 1.1) in the Solar System’s interplanetary dust cloud.

From star +‎ dust.[1]
