Biosphere 2

Biosphere 2

The Biosphere 2 is open to the public. The Experience app allows visitors to explore the world-class research facility safely and at their own pace. A new one-way, ADA-accessible path allows for physical distancing throughout the grounds and the biomes under the glass.



About Biosphere 2

Biosphere 2 serves as a laboratory for controlled scientific studies, an arena for scientific discovery and discussion, and a far-reaching provider of public education. Its ability to combine varying scales, precise manipulation and fine monitoring together in controlled experiments provides scientists with the unique opportunity to explore complex environmental questions.

In this one-of-a-kind facility, UA researchers are using the Landscape Evolution Observatory, the world's largest laboratory experiment in earth sciences, to answer questions about how physical and biological processes control the evolution of landscapes and how water flows through the environment. In the simulated rainforest, scientists are studying how plants cope with high temperatures and drought to better understand how climate change may affect forests. Outside, researchers are growing plants beneath solar panels, pairing renewable energy with agriculture as they explore innovative ways to grow nutritious food crops while increasing energy output.

The University of Arizona has supported Biosphere 2 research since it took over management of the iconic facility in 2007. The University acquired the facility in 2011.
