Video of the Day: Sky with No Light Pollution
The footage was supported by the International Dark-Sky Association. The goal of the project is to explain Skyglow phenomenon which is when the lights of a city diffuse in low layers of the atmosphere and make stars invisible.
To show what residents of megalopolises are missing, the photographers made a time lapse video of Los Angeles at night and combined it with a video of starry nights in the remote places of North America.
Recently they started a Kickstarter campaign to collect money for publishing a book on astrophotography. You can support the project until May 9th.
