The Story Behind This Arizona Biodome Is Both Fascinating And Controversial

Located in southern Arizona just beyond the Santa Catalina Mountains sits a research facility that looks a little oddly placed. To some, it looks like a massive greenhouse and to others, it looks like something from a sci-fi movie about space colonization. Neither assumption would be wrong. In fact, both would be pretty close to the truth about the facility known as Biosphere 2.

Biosphere 2 is located at 32540 South Biosphere Road in Oracle, about 31 miles north of downtown Tucson. For details about visiting the facility, check out their website, And if you’ve paid a visit to this place, be sure to share your experience with us!
