Su-Shu Huang, an American astrophysicist, first introduced the term "habitable zone" in 1959 to refer to the area around a star where liquid water could exist on a sufficiently large body, and was the first to introduce it in the context of planetary habitability and extraterrestrial life.
In astrobiology and planetary astrophysics, the galactic habitable zone is the region of a galaxy in which life might most likely 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 ...
This is a list of unconfirmed exoplanets discovered or detected by the NASA Kepler mission (Kepler Candidates from the NASA Exoplanet Archive) that are potentially habitable. [1] [2] Those already confirmed are listed by their Kepler names in the list of potentially habitable exoplanets, and the data may differ when the planets are confirmed.
The James Webb Space Telescope investigated a giant planet, K2-18b, that could be an ocean world, according to NASA. The exoplanet lies 120 light-years away from Earth.
KOI-1686.01 was also considered a potentially habitable exoplanet after its detection in 2011, until proven a false positive by NASA in 2015. [ 72] Several other KOIs, like Kepler-577b and Kepler-1649b, were considered potentially habitable prior to confirmation, but with new data are no longer considered habitable.
R. Hurt/JPL-Caltech/NASA. ... Gliese 12b still falls within the habitable zone — the ideal distance away from a star where liquid water can exist — even though it completes its orbit every 12. ...
On 17 May 2021, an international team of scientists, including researchers from NASA's Jet Propulsion Laboratory and the University of New Mexico, reported, and confirmed by a ground based telescope, the space telescope's first discovery of a Neptune-sized exoplanet, TOI-1231 b, inside a habitable zone.
273 K (0 °C; 32 °F). [3] Kepler-440b (also known by its Kepler Object of Interest designation KOI-4087.01) is a confirmed super-Earth exoplanet orbiting within the habitable zone of Kepler-440, about 850 light-years (261 pc) from Earth. [1] The planet was discovered by NASA 's Kepler spacecraft using the transit method, in which the dimming ...
