List of potentially habitable exoplanets - Wikipedia
The following list includes some of the potentially habitable exoplanets discovered so far. It is mostly based on estimates of habitability by the Habitable Worlds Catalog (HWC), and data from the NASA Exoplanet Archive. The HWC is maintained by the Planetary Habitability Laboratory at the University of Puerto Rico at Arecibo. [1]
Largest Batch of Earth-size Habitable Zone Planets Found …
In a press release on February 22, 2017, NASA announced the discovery of the most Earth-sized planets found in the habitable zone of a single star, called TRAPPIST-1. This system of seven rocky worlds–all of them with the potential for water on their surface – is an exciting discovery in the search for life on other worlds.
Habitable Exoplanet Observatory (HabEx) - NASA Jet …
2021年11月4日 · The Habitable Exoplanet Observatory (HabEx) is a concept for a mission to directly image planetary systems around Sun-like stars. HabEx will be sensitive to all types of planets; however its main goal is, for the first time, to directly image Earth-like exoplanets, and characterize their atmospheric content.
PHL @ UPR Arecibo - The Habitable Exoplanets Catalog
The Habitable Exoplanets Catalog (HEC) is an online database of potentially habitable world discoveries for scientists, educators, and the general public. The catalog identifies, classifies, and compares exoplanets of interest for the search for life in the universe.
Webb Discovers Methane, Carbon Dioxide in Atmosphere of K2-18 b
2023年9月11日 · K2-18 b, an exoplanet 8.6 times as massive as Earth, orbits the cool dwarf star K2-18 in the habitable zone and lies 120 light-years from Earth. A new investigation with NASA’s James Webb Space Telescope into K2-18 b has revealed the presence of carbon-bearing molecules including methane and carbon dioxide.
