The earth at night


I'll defer any ranting about light pollution in order to sort of marvel with awe at how humans are transforming our planet.  The location is beneath the fold to allow you to have a go at figuring out the location being photographed.

From a collection of satellite photos posted at The Guardian:

The city lights of Spain and Portugal define the Iberian peninsula. Several large metropolitan areas are most clearly visible, including Madrid – located near the centre of the peninsula’s interior – and Lisbon aong the south-west coastline. Though obscured, the lights of France are visible near the horizon line on the upper left, while the lights of northern Africa are more clearly discernable at right. The faint gold and green line is airglow, caused by ultraviolet radiation exciting the gas molecules in the upper atmosphere.

  1. This was one of the most breathtaking videos I think I've ever seen. I hope you enjoy it.

  2. It is fascinating, but it moves so fast, and I keep freezeframing to try to figure out what is where.

    Do you know where the orange "ribbon"-like structure (?highway) is at 3:47 in the video?

  3. I'm thinking now that the ribbon is the Indian-Pakistani border viewed from the northwest(ish).

    Thank you, anon.
