Very Large Array: Located outside of Socorro, New Mexico, this astronomical radio observatory consists of 27 radio antennas. These antenna have been pointed towards the sky for decades and have helped astronomers make numerous discoveries including finding ice on Mercury.
Cabinet War Rooms: Located in London, this underground bunker sheltered and served as the British government command center during World War II. It displays many of the technologies used during the war.
Hayden Planetarium: Probably one of, if not the best planetariums located in the U.S. (New York in fact). Directed by Neil deGrasse Tyson himself, this planetarium offers daily shows on the birth of the universe through the use of an incredible full-dome, high-resolution video system in its Hayden Sphere Star Theatre.
Soudan Underground Mine State Park: "This 19th-century iron mine in the boreal forests of Minnesota has been repurposed as one of the deepest physics experiments in North America—and the deepest that's open to the public. In this subterranean lab, a neutrino detector looks for changes in subatomic particles emitted 460 miles away at the Fermilab particle accelerator. Another experiment searches for dark matter. Visitors take a three-minute mine-cage ride for a physics lesson half a mile below the Earth." (Popular Science)
Museo Galileo: Located in Italy, this museum houses Galileo’s tools (even a couple of his fingers), as well as many artifacts from the 15th to 19th centuries, many of which were pioneering scientific instruments.
Center for PostNatural History: The center houses and displays organisms that have been altered by humans through methods like selective breeding and genetic engineering. It's located in Pennsylvania.
Mercer Museum: Henry Mercer, a 19th-century anthropologist, wanted future generations to know what the past looked like. He began collecting handmade objects that were slowly becoming obsolete and displayed them in a 6-story concrete castle he made near his home. Today the collection, located in Pennsylvania, houses nearly 40,000 objects.
Body Worlds: "Body Worlds is a traveling exhibit created by Gunther Van Hagens, who invented a plastination technique to preserve real human bodies. The exhibit features real human bodies doing different physical and mental activities, allowing people to see the exact nature of the inside of the human body." (BuzzFeed)
