Earth gazing: best view of Earth ever

I love this photo posted at NASA’s Astronomy Photo of the Day of astronaut Tracy Caldwell Dyson gazing out the window from the International Space Station. I agree with Madeleine Robins that this picture is “the perfect cover for the perfect unwritten/unread SF novel I wanted to read when I was thirteen.” Also, is it me or does astronaut Dyson have a Tilda Swinton vibe here?
