World’s Largest Science Experiment: Biosphere 2
Biosphere 2 is the largest closed system ever created. It was built to learn about the Earth’s ecosystems.
It is located in Oracle, Arizona and has been owned by the University of Arizona since 2011. Its mission is to serve as a center for research, outreach, teaching, and lifelong learning about Earth, its living systems, and its place in the universe.
