<font face="arial, helvetica, sans-serif">Neutrinos
are all around us, yet many of their properties remain a mystery. The
study of neutrinoless double beta decay can shed light on the
properties of neutrino mass and whether or not the neutrino is its own
anti-particle. In addition, because neutrinoless double beta decay
violates lepton number conservation, its discovery would lead the way
to physics beyond the standard model. The Enriched Xenon Observatory
(EXO) program is aimed at searching for this decay in Xe-136. I will
discuss the recent results from EXO-200 which has observed the
two-neutrino double beta decay process for the first time in Xe-136 -
the slowest directly-measured nuclear process to date!</font><br>
