Habitability is the conformance of a residence or abode to the implied warranty of habitability. [circular definition] A residence that complies is said to be habitable.It is an implied warranty or contract, meaning it does not have to be an express contract, covenant, or provision of a contract.
A hycean planet is a hypothetical type of planet with liquid water oceans under a hydrogen atmosphere. [1] The presence of extraterrestrial liquid water makes hycean planets regarded as promising candidates for planetary habitability.
Although the ESI does not characterize habitability, given the point of reference is the Earth, some of its functions match those used by habitability measures.As with the definition of the habitable zone, the ESI uses surface temperature as a primary function (and the terrestrial point of reference).
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.
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 .
The supergalactic habitable zone takes into account events in galaxies that can end habitability not only in a galaxy, but all galaxies nearby, such as galaxies merging, active galactic nucleus, starburst galaxy, supermassive black holes and merging black holes, all which output intense radiation. The supergalactic habitable zone also takes ...
The habitability of neutron star systems is the potential of planets and moons orbiting a neutron star to provide suitable habitats for life. [1] Of the roughly 3000 neutron stars known, only a handful have sub-stellar companions. The most famous of these are the low-mass planets around the millisecond pulsar PSR B1257+12.
In astrobiology and planetary astrophysics, the galactic habitable zone is the region of a galaxy in which life is most likely to develop. The concept of a galactic habitable zone analyzes various factors, such as metallicity (the presence of elements heavier than hydrogen and helium) and the rate and density of major catastrophes such as supernovae, and uses these to calculate which regions ...
