The Earth at Night

My sister showed me this a long time ago and I was astounded. It's a composite of hundreds of pictures taken from space. It really puts things into perspective, like how we of different cultures and nationalities think we're so different but we're really the same, like how we've developed differently. And many other political and social assumptions can be made just by studying this photo. For instance, look at the difference between North and South Korea. And look at the Nile River. Just amazing.
