The line in the sky is the International Space Station, 262 miles above the earth. The ISS orbits the earth every 93 minutes at speeds of over 17,000 mph. When it passes overhead, the ISS becomes brighter than any star and can take as long as 6 minutes to cross the sky. There are many apps and websites (such as http://spotthestation.nasa.gov/) that tell you when to look for it.
In the foreground is a mysterious abandoned structure that resembles a lighthouse. I don't know how old it is or what it was built for. I first found it a few months ago at Banner Marsh near the Illinois River.
