The habitability of natural satellites is the potential of moons to provide habitats for life, though it is not an indicator that they harbor it.Natural satellites are expected to outnumber planets by a large margin and the study of their habitability is therefore important to astrobiology and the search for extraterrestrial life.
Europa – possible effect of radiation on biosignature chemicals. So far, there is no evidence that life exists on Europa, but the moon has emerged as one of the most likely locations in the Solar System for potential habitability.
Internal structure of Europa. The blue represents a subsurface ocean. Such subsurface oceans could possibly harbor life. [55] Europa may have a liquid ocean beneath its icy surface, which may be a habitable environment. This potential ocean was first noticed by the two Voyager spacecraft, and later backed by telescope studies from Earth.
A SpaceX Falcon Heavy rocket carrying NASA's Europa Clipper space probe launches from Kennedy Space Center on Oct. 14, 2024, on a mission to orbit Jupiter and study its icy moon, Europa, for signs ...
The following list includes some of the potentially habitable exoplanets discovered so far. It is mostly based on estimates of habitability by the Habitable Worlds Catalog (HWC), and data from the NASA Exoplanet Archive.
Planetary habitability is the measure of a planet's or a natural satellite's potential to develop and maintain an environment hospitable to life. [1] Life may be generated directly on a planet or satellite endogenously. Research suggests that life may also be transferred from one body to another, through a hypothetical process known as ...
Europa On Earth, subglacial microbial communities at Blood Falls survive in cold darkness without oxygen, living in brine water below Taylor Glacier, but come out at this location in Antarctica. The red color comes from dissolved iron. The Europa Lander is an astrobiology mission concept by NASA to send a lander to Europa, an icy moon of Jupiter.
Ganymede view by the Galileo spacecraft Section of Europa's icy surface, viewed from Galileo. The Juice orbiter will perform detailed investigations on Ganymede and evaluate its potential to support life. Investigations of Europa and Callisto will complete a comparative picture of these Galilean moons. [26]
