Astronomers found out an additional condition, necessary for the origin of life. It was considered to the real moment, that by a necessary condition for appearance of living organisms there is a presence of liquid water on ekzoplanetakh. For implementation of this condition a planet must bed in the so urgent area of inhabited - an enough narrow area of space is around zvezdy-khozyaina. If the orbit of planet passes too close from a luminary - water will evaporate. When a planet applies
far from a star - water is in a state of ice.The authors of new research prove that among planets, being in the area of inhabited, far not all can serve "by cradles" for the origin of life. Suitable candidates there are only planets, on
which flows or active volcanic activity flowed. During eruption carbon dioxide and aquatic steam, hidden in the bowels of the earth, is thrown out on a surface and carried on large distances. Terms, playing in favour of to the process, are thus created
photosynthesis - to formation of organic matters from CO2 H2O under act of radiation.However important planets are "not to overdo" with volcanic activity. Too strong eruptions at which all surface of planet is constantly inundated by lava do not promote
to appearance of living creatures.Eruptions of volcanos are caused by the action of flood-tide forces. Flood-tide forces arise up at affecting planet of one or a few massive bodies. Thus, for the estimation of potential inhabited of planet it is necessary to take into account not
only its position in relation to a star, but also its space surroundings.As an example works of the theory astronomers chosen ekzoplanetu GJ 581 d, remote from Earth on 20 light years. In spite of "correct" for the potentially inhabited planet of description,
gravity influence on GJ 581 d from the side of neighbours not enough in an order to stimulate volcanic activity in a sufficient measure.A search of life outside Earth is to one of important aims of astronomic researches. Scientists search life
not only on remote planets, but also on to
chances of Encelada "to generate" living creatures, reports Lenta.ru. For the estimation of potential inhabited of planets it is important to take into account their space surroundings. Image NASA/JPL-Caltech
