This picture of Chicago was tweeted from the International Space Station by Commander Chris Hadfield. (Tweets from space!). It shows Chicago from space orbit (click to enlarge), and was taken yesterday. Hadfield’s note:
Chicago on a clear winter’s day, ice on the shore, busy O’Hare airport visible from orbit.
O’Hare is obvious, about halfway up from the center on a line bisecting the photo vertically. I’ve added a red arrow to show you where I am (I think!).
