So as to prepare future observations of terrestrial extrasolar planets liable to shelter life, we attempt to detect
the life on the Earth seen as a dot. We use the Moon Earthshine, in which any place reflects the totality of the
enlightened part of Earth facing the Moon. Observing from OHP and from ESO, we detected terrestrial chlorophyll in
the near infrared, the so-called Vegetation Red Edge, and this detection is larger when forests are present than
when an ocean is mainly visible from the Moon. Only if observations are made from a high latitude location, and
at some moments in the year, Earthshine can be observed during a large part of the day. During these long observing
windows, different “landscapes" are facing the Moon. So the Earthshine corresponding to various parts of our Earth
could be studied. Preliminary testing observations have been made at Concordia since the first winterover campaign
and the LUCAS experiment has been set up.
