Habitable Worlds
Habitable worlds or potentially habitable exoplanets news and latest updates on terrestrial planets which can maintain liquid water on its surface with conditions similar to that on Earth.
Habitable Exoplanets Catalog (HEC), Planetary Habitability Laboratory and Circumstellar habitable zone (CHZ) such as Proxima Centauri b, Gliese 667Cc 832c, Kepler 442b 452b 1229b 438b 296e 62e, and Wolf 1061c to name a few ecosphere, liquid-water belt, life zone or Goldilocks zone.

Apr 16, 2021Oxygen in the atmosphere may not be an entirely reliable 'biosignature,' but there are ways to distinguish false positives from signs of life -
Apr 12, 2021To confirm life on other planets, we need to detect far more molecules in their atmospheres than we currently do -
Jul 11, 2020NASA has stepped closer to allowing remote onboard computers to direct the search for life on other planets. -
Apr 27, 2020Every rock tells a story, and so does each fatty acid called a lipid. Your cholesterol, which is part lipid and part protein, could last for billions of years, and contains the information that you are a mammal. Could we find lipids beyond Earth? NASA -
Jan 21, 2020New study finds surface waters on early Mars may have been habitable for microbial life -
Jan 10, 2020NASA’s Transiting Exoplanet Survey Satellite (TESS) has discovered its first Earth-size planet in its star’s habitable zone, the range of distances where conditions may be just right to allow the presence of liquid water on the surface. -
Nov 14, 2019First study to combine 3D climate modeling with chemistry explores M dwarf planets -
Nov 7, 2019Contrary to previous thought, a gigantic planet in wild orbit does not preclude the presence of an Earth-like planet in the same solar system - or life on that planet. -
Oct 14, 2019In a recent paper, Harvard University researchers described a new, lower size limit for planets to maintain surface liquid water for long periods of time, extending the so-called Habitable or "Goldilocks’’ Zone for small, low-gravity planets. -
Oct 13, 2019Its size and surface gravity are much larger than Earth’s, and its radiation environment may be hostile, but a distant planet called K2-18b has captured the interest of scientists all over the world. For the first time, researchers have detected water vapor signatures in the
