SUMMARY:The present and future of solar neutrinos with Borexino\, Phys
 ics Department Colloquium\, Andrea Pocar\, University of Massachusetts
 \, Amherst
DESCRIPTION:Borexino is a large\, low-energy neutrino experiment that 
 has been running since 2007 at the Gran Sasso underground laboratory i
 n Italy.  It is the only running detector potentially sensitive to the
  entire solar neutrino spectrum. It has so far made the first measurem
 ent of the Berillium-7 neutrinos\, now known with 5% precision\, measu
 red the Boron-8 neutrinos with lower energy threshold than previous ex
 periments\, and observed pep neutrinos for the first time.  More recen
 tly\, Borexino made the first direct detection of pp neutrinos.  These
  are the most abundant solar neutrinos\, yet they have proven very har
 d to detect due to their low energy and the presence of the Carbon-14 
 background in organic scintillator.  These results will be described i
 n detail\, in the context of neutrino and solar physics. The  Borexino
  program for the coming years will also be presented\, with particular
  focus on the hunt for CNO solar neutrinos.
