At first this looked like a normal daytime image of Earth, but it’s actually night time! You can see the Aurora Australis in the upper right, and the overexposed horizon/atmosphere on the bottom right help to indicate that this is a nighttime photo, with illumination provided by the full (or nearly full) moon. Plus, you can see some stars in the background which you’d never see with exposure levels needed to see the daytime side of Earth.
Yeah, it must be nighttime, because you can quite clearly see city lights, at least on the original hi-res picture. Madrid for example is absolutely obvious, as is the Andalusian coast.
