Explanation: Where have all the dim stars gone? From many places on the Earth including major cities, the night sky has been reduced from a fascinating display of thousands of stars to a diffuse glow through which only a few stars are visible. The featured map indicates the relative amount of light pollution that occurs across the Earth. The cause of the pollution is artificial light reflecting off molecules and aerosols in the atmosphere. Parts of the Eastern United States and Western Europe colored red, for example, have an artificial night sky glow over ten times that of the natural sky. In any area marked orange or red, the central band of our Milky Way Galaxy is no longer visible. The International Dark Sky Association suggests common types of fixtures that provide relatively little amounts of light pollution.

North Korea, Tibet, Greenland, northern Canada, interior parts of Australia and Africa look like good bets. Book your flights today and beat the crowds.

Parts of Iraq and Algeria look unusually bright. Could be gas flares.

It’s always a little funny to realize how dense the population is in the US east of the Mississippi. Moving west, things change dramatically. Obviously, it’s not North Korea/South Korea different, but that big swath around the Rockies is pretty dark and empty.
