    Astronomy and telescopes also improved to the point exoplanets can be confirmed and even studied, increasing the number of search places. Life may still exist elsewhere in the Solar System in unicellular form, but the advances in spacecraft allow to send robots to study samples in situ, with tools of growing complexity and reliability.

  3. Life origination beyond planets - Wikipedia

    Life in the atmosphere brown dwarfs was also discussed by Yates et al. in 2017, and in 2019 Manasvi Lingam and Abraham Loeb extended the discussion of Yates et al.. Both articles extend the viability of Earth-like biological life beyond planets. [8] [9] Their ideas were criticized by experts in brown dwarfs. [10]

  4. Astrobiology - Wikipedia

    en.wikipedia.org/wiki/Astrobiology

    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.

  5. Planetary habitability - Wikipedia

    en.wikipedia.org/wiki/Planetary_habitability

    Understanding planetary habitability is partly an extrapolation of the conditions on Earth, as this is the only planet known to support life.. Planetary habitability is the measure of a planet's or a natural satellite's potential to develop and sustain an environment hospitable to life. [1]

  6. Habitability of natural satellites - Wikipedia

    en.wikipedia.org/wiki/Habitability_of_natural...

    An atmosphere is considered by astrobiologists to be important in developing prebiotic chemistry, sustaining life and for surface water to exist. Most natural satellites in the Solar System lack significant atmospheres, the sole exception being Saturn's moon Titan. [19]

  7. Rare Earth hypothesis - Wikipedia

    en.wikipedia.org/wiki/Rare_Earth_hypothesis

    The Rare Earth hypothesis argues that planets with complex life, like Earth, are exceptionally rare.. In planetary astronomy and astrobiology, the Rare Earth hypothesis argues that the origin of life and the evolution of biological complexity, such as sexually reproducing, multicellular organisms on Earth, and subsequently human intelligence, required an improbable combination of astrophysical ...

    This is a list of 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.
