The millions of tourists who visit the Smithsonian Museum each year see a number of exhibits that are enough to impress most people. But there's a secret vault at the museum that houses some of the coolest stuff in the Smithsonian's collection. These hidden storerooms aren't meant to be seen by the general public, but in this series, host Xavier Carnegie -- the creative director at the National Museum of American History -- gives some unsuspecting Smithsonian guests the opportunity to enter those vaults to witness hidden gems firsthand. Others may be whisked away on a trip to explore America. All the visitors have to do to earn these once-in-a-lifetime experiences is answer some trivia questions that Carnegie asks them.

Some of the most fascinating stories in the world's most famous museums are hidden in restricted areas, including backrooms and basements, that are not accessible by members of the public. "Museum Secrets Revealed" takes viewers behind the scenes at museums around the world to highlight obscure collections and use cutting-edge research to unlock their secrets, as promised in the title. Among the facilities explored in the series are the Louvre in Paris, New York's Metropolitan Museum of Art, and Mexico City's National Museum of Anthropology.

Golden Globe-nominated actor Jason Priestley is the narrator of this series that explores the stories behind some of the world's most enigmatic mummies. With the series spanning four continents and more than 5,000 years, each episode focuses on one mummy, investigating the preserved remains and using CGI to bring the cadaver -- and its story of a past civilization -- to life. The featured mummies include one on display at a shop in downtown Seattle and another that was discovered frozen on a glacier in the Italian Alps.

Some people like to hop in a car to take a road trip across America, visiting as many landmarks as possible along the way. Since such a trek can take a while to complete, taking a flight across America might be a better option for some people. "Aerial America" takes viewers on such a flight, offering rare looks at some of the nation's best-loved landmarks from high in the sky. Cameras capture the history and pageantry of America as they zoom over busy cityscapes and quiet, rural lands. Many episodes focus on a specific state, showcasing highlights of the state's beauty, while others revolve around themes such as the best small towns and natural wonders found in the country.
