Neutrinos are impervious to the strong and electromagnetic forces and their minuscule weak interactions allow them to freely escape from the deep of the stars or of the Earth bringing precious information about regions otherwise inaccessible. Borexino is a large, unsegmented liquid-scintillator calorimeter in operation at the Laboratori Nazionali del Gran Sasso (LNGS) in Italy, since 2007. The record-high radio-purity is the basis of the outstanding achievements obtained by the experiment over the 10-year long data taking. This contribution is aimed at reviewing the most recent Borexino results in the field of the solar and geo-neutrino physics, namely the measure of the fundamental pp solar neutrino flux, which is the direct probe of solar thermonuclear fusion reactions, and the measure of the geo-neutrino signal with its geophysical implications.
