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.
An understanding of planetary habitability begins with the host star. [19] The classical habitable zone (HZ) is defined for surface conditions only; but a metabolism that does not depend on the stellar light can still exist outside the HZ, thriving in the interior of the planet where liquid water is available. [19]
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.
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.
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 ...
Talk about a tale of two cities. A new report calls New York one of the best cities in the country for an active lifestyle — while a spot right across the Hudson River ranks as one of the worst ...

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).
