Habitability has been generally defined as the capability of an environment to support life.
Ecologists have been using Habitat Suitability Models (HSMs) for more than four decades to …

The field of prebiotic chemistry has demonstrated that complex organic chemical systems
that exhibit various life-like properties can be produced abiotically in the laboratory …

The emergence of life from nonlife, or abiogenesis, remains a fundamental question in
scientific inquiry. In this article, we investigate the probability of the origin of life (per …

The probability that life spontaneously emerges in a suitable environment (abiogenesis) is
one of the major unknowns in astrobiology. Assessing its value is impeded by the lack of an …

In the solar system, Icy Worlds such as Europa and Enceladus hold great potential for
extraterrestrial life and may provide humanity an answer, within this century, to the age-old …

Life on our planet likely evolved in the ocean, and thus exo-oceans are key habitats to
search for extraterrestrial life. We conducted a data-driven bibliographic survey on the …

The term “habitability” is pervasive throughout the space sciences and astrobiology literature
and is broadly used to describe an environment's ability to support life. Here, we argue that …

This study investigated what defines the limits of life in mixed ion solutions. Better
understanding these limits should allow us to better predict the habitability of extreme …

Beneath Enceladus' ice crust lies an ocean which might host habitable conditions. Here, the
scale and productivity of a notional Enceladean methanogenic biosphere are computed as a …

To the Editor—In their recent Comment, Cockell et al. 1 argue that the habitability of an
environment is fundamentally a binary property; that is to say, an environment can either …
