Low Energy solar neutrino detection plays a fundamental role in understanding
both solar astrophysics and particle physics. After introducing the open
questions on both fields, we review here the major results of the last two
years and expectations for the near future from Borexino, Super-Kamiokande, SNO
and KamLAND experiments as well as from upcoming (SNO+) and planned (LENA)
experiments. Scintillator neutrino detectors are also powerful antineutrino
detectors such as those emitted by the Earth crust and mantle. First
measurements of geo-neutrinos have occurred and can bring fundamental
contribution in understanding the geophysics of the planet.Comment: 18 pages, 36 figures, proceedings of XXV Lepton Photon, 22 to 27
