Many Habitable Worlds to Choose From


The objective of the Prototype Habitable Exoplanets (PHE) project is to explore the potential different scenarios for habitable exoplanets suitable for terrestrial life. In particular, we are interested in those planets on the threshold of habitability, Earth-, and those optimum for life, Earth+. This is an ongoing multidisciplinary project trying bottom-top definitions of habitable exoplanets. More details soon.

Current Results

  • There are many types for habitable planets, some probably even better for life than Earth.
  • Earth+ planets are more habitable than Earth and easier to detect than Earth-like planets.
  • We might have already detected and Earth+ planet, but confirmation will take many years of additional observations.
