The border between India and Pakistan is one of the heavily guarded and lit stretch in the world, so much that it can be seen from space at night. It covers an immense distance from the Arabian Sea to the Himalayan foothills.

Here is how it looks from ISS. [India-Pakistan Border at Night from NASA Earth Observatory][1]

> The winding border between Pakistan and India is lit by security lights that have a distinct orange tone. The port city of Karachi is the bright cluster of lights facing the Arabian Sea. For scale, the distance from Karachi to the foothills of the Himalaya Mountains is 1,160 kilometers (720 miles)
