The city at the center is Milwaukee. Above Milwaukee in the photo is Waukesha. It is a 2012 photo from Expedition 30 of the International Space Station. The line of lights connecting the two cities comes from vehicles and development on and along Bluemound Road and I-94. Due to the angle of the photo, north points rightwards, and west upwards. To the left of Milwaukee along the lakeshore are the cities of Racine, Kenosha, and Waukegan. Kenosha and Waukegan are considered part of the Chicago CSA rather than part of metro Milwaukee. The lights in the far left along the lake are from a portion of Cook County, of which Chicago is the county seat. To the right of Milwaukee are Cedarburg and Grafton. Port Washington is just to the right of Grafton and along the lakeshore. Above Port Washington, the "+" shaped lights are from West Bend. In the far right edge, a small portion of Sheboygan can be seen along the lakeshore.
