  Detection and characterization of potentially habitable Earth-size extrasolar
planets is one of the major goals of contemporary astronomy. By applying the
transit method to very low-mass M-dwarfs, it is possible to find these planets
from the ground with present-day instrumentation and observational techniques.
The MEarth project is one such survey with stations in both hemispheres:
MEarth-North at the Fred Lawrence Whipple Observatory, Mount Hopkins, Arizona,
and MEarth-South at Cerro Tololo Inter-American Observatory, Chile. We present
an update on recent results of this survey, for planet occurrence rates, and
interesting stellar astrophysics, for which our sample of 3000 nearby
mid-to-late M-dwarfs has been very fruitful. All light curves gathered during
the survey are made publicly available after one year, and we describe how to
access and use these data.
