Look at a photo at dusk of Europe and Africa, on a clear day, without clouds, from a satellite in orbit.

Observe how the lights are switched on in Paris and Barcelona, but not in London, Lisbon nor Madrid where the day is still clear.

In the middle of the Ocean you can identify the Azores, Madeira, and beyond the Canary Islands and Cape Verde.

The most impressive is the perfect display of Continental Shelves from the British Islands to Canada and the centre of Iceland.

These first pictures from a satellite, show us the beginning of dusk any day.

The first photo gives us a real view and the second, through a satellite effect, highlights the lights of the cities in the United States.

In the Caribbean we can see the high brightness in Puerto Rico, especially the metropolitan San Juan and the north coast of its entire circumference.

What a spectacle !What a spectacle !

This photo gives us a vision of the United States at dusk.

If you are surprised by the number of cities highlighted by the lights…

We see a greater number of cities, but due to the amount of lights it is difficult to know what it is!
