The interdisciplinary field of Astrobiology constitutes a joint arena where provocative discoveries are coalescing concerning, e.g. the prevalence of exoplanets, the diversity and hardiness of life, and its increasingly likely chances for its emergence. Biologists, astrophysicists, biochemists, geoscientists and space scientists share this exciting mission of revealing the origin and commonality of life in the Universe. The members of the different disciplines are used to their own terminology and technical language. In the interdisciplinary environment many terms either have redundant meanings or are completely unfamiliar to members of other disciplines.

The Encyclopedia of Astrobiology serves as the key to a common understanding. Each new or experienced researcher and graduate student in adjacent fields of astrobiology will appreciate this reference work in the quest to understand the big picture. The carefully selected group of active researchers contributing to this work and the expert field editors intend for their contributions, from an internationally comprehensive perspective, to accelerate the interdisciplinary advance of astrobiology.

It is considered to be one of the driest places on Earth with average annual rainfall of less than 1 mm in some locations. It is a useful analog to the arid surface of Mars and for analog studies of hydrology, mineralogy, and microbiology. Features that may be analogous to Mars also

In the Archean (inset b), geothermal gradient along Benioff plane was very high; subducted slab melts at shallow depth before dehydration could take place. After 2.5 Ga, Earth was cooler and the geothermal gradient along the Benioff plane was lower (inset c) such that slab dehydration generally occurs before
