Habitable Zones & Global Climate: January 2014


Earth-scale planets in the classical habitable zone (HZ) are more likely to be habitable if they possess active geophysics.

We make a preliminary assessment on the habitability of potential rocky exoplanets around Alpha Centauri B.

Superhabitable Worlds

To be habitable, a world (planet or moon) does not need to be located in the stellar habitable zone (HZ), and worlds in the HZ are not necessarily habitable.

Astrobiologists supported by the NASA Astrobiology Institute have found that a peculiar feature in the atmosphere of Earth could also be present on billions of extrasolar planets.

A general formulation to compute habitable zones for binary stars is presented.

Massive terrestrial planets, called "super-Earths," are known to be common in our galaxy, the Milky Way.

Large terrestrial planets are expected to have muted topography and deep oceans, implying that most super-Earths should be entirely covered in water, so-called waterworlds.

We have developed a comprehensive methodology and an interactive website for calculating the habitable zone (HZ) of multiple star systems.
