The Borexino solar-neutrino detector is a high-radiopurity lowthreshold liquid scintillator that detects solar neutrinos by means of the elastic scattering νe → νe reaction. The detector, located at the Laboratori Nazionali del Gran Sasso (LNGS, Italy) and has now measured solar neutrinos from the 7Be, 8B and pep components. Terrestrial neutrinos (geoneutrinos) have also been observed
