Microlensing technique used to detect extrasolar planets is sensible to low-mass planets orbiting a few AU away from their stars. The detection of OGLE-2005-BLG-390Lb (hereafter, OGLE-390Lb) around an M star from the Galactic bulge (Beaulieu et al. 2006) unveil the existence of few-Earth-masses and cold (˜40 K) planets. These frozen planets might nonetheless host liquid water underneath an ice shell, due to a strong radiogenic heating at the bottom of the ice layer. Heating and cooling are depending upon the mass ratio ice/rock and the age of the planet. OGLE-390Lb seems too old to have a subsurface ocean for any value of the ratio ice/rock; however, liquid water below an ice shell was certainly present in the past for several billion years. See Ehrenreich et al. (2006b) for details.
