The skyline of Chicago, Illinois, USA, as seen from the Adler Planetarium. The scene stretches from Shedd Aquarium on the left to Navy Pier on the right. In between, other Chicago landmarks can be seen, such as, from left to right, Sears Tower (tall black building), the Aon Center (tall white building), and the John Hancock Center (black trapezoidal building).Photo credit: Buphoff
