biospheres

Life-supporting planetary regions

Biospheres are regions capable of supporting life.

Earth's biosphere encompasses all living organisms and the environments they inhabit—from ocean depths to the upper atmosphere.

The term also applies to artificial enclosed ecosystems designed to sustain life independently: The experiment sealed volunteers inside a biosphere for two years.

In science fiction, biospheres often appear as self-contained habitats on spacecraft or other planets.
