Chicago's Adler Planetarium is one of the city's most popular attractions, and with good reason. Comprised of a museum which exhibits many fascinating items, including the space suit of one Buzz Aldrin, as well as a plethora of family-friendly educational games where kids can learn just how outer space operates, there's plenty to take in on a wander around this fantastic attraction.

With videos showing media coverage of the first moon landing, as well as original newspapers from the period, if you've ever wanted to learn about the history of astronomical adventure, this is where to go. What's more, there are fantastic movies to take in that explain a world of information about the galaxy and beyond - narrated by famous actors like Whoopi Goldberg - as well as the planetarium's key attraction, the Sky Theatre planetarium. This theatre is the dome that can be seen from the outside of the building, which characterises its appearance. Inside, guests will be treated to a live show of the stars: an expert staff use a Zeiss projector to place an image of the stars on the roof of the dome, giving the illusion of literally being surrounded by the night sky, and regale visitors with fascinating stories about constellations, including some dipping into ancient Greek mythology about the star signs, heroes of the land, and all-powerful gods.

The Adler Planetarium has reached such popularity that it is now represented on the Chicago city pass, a pass which offers huge discounts on major attractions. From a one off fee, tourists can purchase the pass and enter attractions such as the city's main museum, the aquarium, the planetarium and enjoy access to boat trips and the top of the Sears building in order to enjoy Chicago's cityscape from above. If you're with friends or family who'd love to take in as much of the city as possible, it's definitely worth grabbing a few passes and enjoying all the best attractions.

However, even if you're just interested in seeing what Chicago has to offer by night, this beautiful city will enable you to enjoy strolling beneath the evening sky and a visit to Navy Pier to see the stars floating above will allow you to see the same view as that displayed in the planetarium.

Whether you're a major astronomy fan or simply interested in finding out more about the galaxy, the Adler Planetarium should be on every tourist's itinerary during their stay in Chicago hotels. You might just find that you won't only want to visit once.
