Planetary habitability in the Solar System is the study that searches the possible existence of past or present extraterrestrial life in those celestial bodies. As exoplanets are too far away and can only be studied by indirect means, the celestial bodies in the Solar System allow for a much more detailed study: direct telescope observation, space probes, rovers and even human spaceflight.
Nucleic acids may not be the only biomolecules in the universe capable of coding for life processes. [1]Astrobiology (also xenology or exobiology) is a scientific field within the life and environmental sciences that studies the origins, early evolution, distribution, and future of life in the universe by investigating its deterministic conditions and contingent events.

The mission to find extraterrestrial life has begun. At 16:06 GMT, NASA launched the Europa Clipper ship from Cape Canaveral, Florida, to search for signs of life on one of Jupiter’s frozen ...
The search for extraterrestrial intelligence (SETI) is a collective term for scientific searches for intelligent extraterrestrial life.Methods include monitoring electromagnetic radiation for signs of transmissions from civilizations on other planets, [1] [2] [3] optical observation, and the search for physical artifacts.

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.
f l = the fraction of planets that could support life that actually develop life at some point. f i = the fraction of planets with life that go on to develop intelligent life (civilizations). f c = the fraction of civilizations that develop a technology that releases detectable signs of their existence into space.
