Summary
editDescriptionHow light pollution affects the dark night skies (dark-skies) (flipped left-right).jpg |
English: This image illustrates the Bortle scale, which measures the impact of light pollution on the dark skies at a given location. It shows, from left to right, the decrease in the number of stars and night-sky objects visible in excellent dark sky conditions compared with cities. The illustration is a modification of an original photograph taken at ESO's Paranal Observatory in Chile, a place with excellent dark-sky conditions, perfect for astronomy. The image has been flipped left to right. |
