The light of the moon on clouds over the Bay of Biscay takes the sheen on this panorama from the International Space Station up a notch or two. Beneath the stars, airglow and a hint of an aurora, busy humans in an arc from Plymouth on the south coast of England (left) to Lisbon, on Portugal's Atlantic coast (right) extend their day with artificial light.
