Milky Way may be the most foreigner of the seven planets (Photos) 2010-05-20 10:06 Source: Sohu IT Author: Jean-force [Comment 0] Milky Way may have discourse up to 400 billion stars, we assume that only a quarter of the stars have planets, but only a quarter of these planets for life to exist.
galaxy may be up to 400 billion stars, we imagine that only a 15 min of the stars have planets, yet merely a quarter of these planets suitable as life, then the Milky Way still has a location there may be hundreds of millions of creatures. Although we have no found extraterrestrial life,
Lacoste Canvas Trainers, yet there are 7 zones most likely to aliens: Mars, Europa, Ganymede, Callisto, Titan, Enceladus,
Womens Lacoste Observe Trainers, Ge Lisi 581d.
a Mars
our solar system, Mars namely maximum favor the planet Earth, either in quondam and present, the likelihood of Martian life exists are quite great, and the evidence is very conclusive. People generally deem namely the most momentous necessities of life - liquid water, past the cross-flow above the planet and over. Mars Global Observer recently issued photos show the Red Planet's surface ashore the cold, there is evidence of fluid flow (this phenomenon occurred in the past decade now).
II Europa
Europa's surface is covered with a thick layer of ice, so it appeared very special. Although a grain of truth the sun, but the cold surface of Europa is likely to exist under a heart full of peppery lava can be heated to the ice, which produces the cold surface of a liquid ocean beneath. This means that it has advocate for micro-organisms or easy factory life conditions, as in hydrothermal vents in the globe, as occurred.
three Titan
Titan is Saturn's largest moon, there is remove evidence that: it is the surface of the lake there is a complete liquid . Although the lakes inside the liquid is not made of water (the makeup of hydrocarbons), but it is a complex alphabetical compounds produced ideal breeding floor. Moreover, Titan's thick air also contains nitrogen and other factors of life to build.
four Enceladus
Enceladus is the sixth largest satellite of Saturn,
Lacoste Tourelle Trainers, though it is relatively small, but they may nurture a life. In fact, Enceladus is the 3 stars in the outer solar system have observed one of the volcanic outbreak of stars. More importantly,
Womens Lacoste Trainers, it's outbreak involve large values of water, so many experts believe that under the surface of the icy satellites there is a liquid ocean. And where there is water, there may be life.
five Tethys
Tethys Saturn's largest moon,
Lacoste Shoes, is the largest satellite in our solar system. Its surface is mainly composed of silicate and water ice, but under the surface of 200 km is thought to constitute the existence of a salt sea,
Lacoste Trainers 2011, the Tethys Ocean sandwiched among the ice. With close to Enceladus, and additional large planets satellites, Tethys has also been the role of tidal heating, which makes it below the surface of a formation to nourish sufficient heat to subserve the formation of liquid water.
six Dione
orbit of Dione is the second largest satellite of Saturn, Enceladus, and than the Tethys are far away from Saturn, so at the tidal heating is fewer important. Nevertheless, many scientists believe it has a layer of liquid water under the surface. Because of its cheap radiation intensity, so the Jupiter system has been considered the most suitable bottom for a hereafter where mankind.
seven Ge Lisi 581d
Ge Lisi 581d is a labeled Geli Si 581 in the Libra star orbit a planet, It is too found further the solar system one of the few Earth-sized planets very one. Gliese 581d situation is very profitable apt the existence of liquid water, so there could be life. Because of its surface is probable covered with deep water, it too became the 1st
