Southern sky survey finds distant worlds



One more step ! A BBC papers ( (copy on )reports the discovery of several planets outside the solar system, in what is referred to as the “habitable zone”. This zone is defined by various constraints (liquid water for instance) and encompasses the zone of a solar system where life as we know it may appear (see the reference book “E.T. Civilization” from the late Isaac Asimov for more details).


However, the discovered planets are as big as Jupiter and most probably consist of gas. Life, should it exist there, may therefore be of an unusual form. Possibly more “common” life forms could be found on some of the natural satellites of these planets.
