Habitable Zones & Global Climate: February 2016

Terrestrial planets at the inner edge of the habitable zone of late-K and M-dwarf stars are expected to be in synchronous rotation, as a consequence of strong tidal interactions with their host stars.

Groundwater circulation beneath a massive tectonic rift zone located along the flanks of some the solar system's largest volcanic plateaus resulted in the formation more than 3 billion years ago of some the deepest basins on Mars, according to a new paper by Planetary Science Institute Senior Scientist J. Alexis Palmero Rodriguez.

The study of cosmology, galaxy formation and exoplanetary systems has now advanced to a stage where a cosmic inventory of terrestrial planets may be attempted.

Terrestrial planets formed within gaseous protoplanetary disks can accumulate significant hydrogen envelopes.
