Some of these appear to be satellite pictures while others (towards the bottom) are fake--or at least composite pictures. If that picture of night falling across Europe (the fourth one down) is real, it's one of the most beautiful pictures I've ever seen.
Wait, it can't be real. There are no clouds anywhere. Maybe it's another of those composite pictures.
I sure wish people would be clear when they create these pictures; it's deceptive not to idenfity them as composite.
