While you may need dark skies away from city lights to be able to enjoy the night sky, it is still possible to enjoy some astronomy-related activities even in the largest cities. Visiting a planetarium or science museum can re-spark your interest to get back out under the night skies. Whenever you happen to be on a break in a large city, it is worth seeking out astronomical-related opportunities which may be coincidental to your visit. In this chapter we explore how museums, exhibitions, and planetaria can deepen our appreciation of the night sky. We will also look at some further topics in astronomy and space that may be of interest to readers.
