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.
Science fiction has communicated scientific ideas, imagined a range of possibilities, and influenced public interest in and perspectives on extraterrestrial life. One shared space is the debate over the wisdom of attempting communication with extraterrestrial intelligence.
Exobiology or astrobiology is the study of the origin and evolution of extraterrestrial life. In terrestrial analogues efforts are put on the identification of so-called extremophile organisms, which are life forms that live and survive in extreme conditions such as can be found on other planets or moons. The objective of this research is to ...
The existence of extraterrestrial life, life outside of Earth, is an ongoing scientific search as well as societal debate. Astrobiology to planetary geology are some of the disciplines interested in finding life elsewhere in space. Astrosociology intersects these by exploring the social dimensions of finding extraterrestrial life – exploring ...
This is a list of confirmed exoplanets within the circumstellar habitable zone that are either under 10 Earth masses or smaller than 2.5 Earth radii, and thus have a chance of being rocky.
Although the report discusses the need for research on many policy issues related to space exploration, it is most often cited for passages from its brief section on the implications of a discovery of extraterrestrial life. (See Section #Use in discussions about possible cover-ups)
The field of astrobiology has its origins in the 20th century with the advent of space exploration and the discovery of exoplanets. Early astrobiology research focused on the search for extraterrestrial life and the study of the potential for life to exist on other planets. [2]
The search for extraterrestrial intelligence (SETI) is a global scientific effort to detect extraterrestrial signals, or evidence of intelligent life beyond earth.. Researchers use methods such as monitoring electromagnetic radiation, searching for optical signals, and investigating potential extraterrestrial artifacts for any signs of transmission from civilizations present on othe
