Th Exelon Observatory on the 606
Time Out says
Located at the western trailhead of the 606, the Exelon Observatory hosts a popular all-ages stargazing series, For the Love of Stars. Chicagoans can learn about the night sky and sunsets with Adler Planetarium astronomers. The space was closed over the summer 2017 for remodeling and landscaping, and will hopefully be back open in spring 201.
