Today’s wallpaper shows the Blanco 4-meter telescope at the Cerro Tololo Inter-American Observatory in Chile. I retrieved this image from the National Optical Astronomy Observatory’s image bank (click on the image for more wallpaper sizes). You know what else they have on offer? A great collection of astronomy-themed wallpapers for your iPhone.
