Milky Way may be the most foreign of the seven planets (Photos) 2010-05-20 10:06 Source: Sohu IT Author: Jean-force [Comment 0] Milky Way may have lecture 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 merely a 15 min of the stars have planets, but only a quarter of these planets suitable for life, then the Milky Way still has a location there may be hundreds of millions of creatures. Although we have not found extraterrestrial life, but there are seven places most likely to aliens: Mars, Europa, Ganymede,
Nike Shox Menn, Callisto, Titan, Enceladus, Ge Lisi 581d.
a Mars
our solar system, Mars is most favor the planet Earth,
Nike Shox R3, both in quondam and present, the potentiality of Martian life exists are very large, and the testify is very conclusive. People generally believe that the most important necessities of life - liquid water, elapse the cross-flow aboard the planet and over. Mars Global Observer recently published photos show the Red Planet's surface ashore the cold, there is evidence of fluid stream (this phenomenon happened in the past decade immediately).
II Europa
Europa's surface is covered with a thick layer of ice, so it seemed very special. Although by inches the sun, but the cold surface of Europa is threaten to exist under a heart full of hot lava can be heated to the ice, which produces the chilly surface of a liquid ocean below. This manner that it has support for micro-organisms or easy plant life conditions, for in hydrothermal vents in the globe, for 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 composition of hydrocarbons), but it is a complicated alphabetical compounds produced ideal propagating floor. Moreover, Titan's thick air also contains nitrogen and other ingredients of life to construct.
four Enceladus
Enceladus is the sixth largest satellite of Saturn,
Nike Shox R3-R4 Combination, although it is relatively small, merely they may nurture a life. In fact,
Nike Shox Monster, Enceladus is the 3 stars in the external solar system have observed one of the volcanic emission of stars. More importantly, it's emission involve great sums of water,
Nike Shox Kvinner, so numerous specialists trust namely beneath the surface of the icy satellites there is a liquid ocean. And where there is water,
Nike Shox TL3, there may be life.
five Tethys
Tethys Saturn's largest moon, is the largest satellite in our solar system. Its surface is primarily composed of silicate and water ice, but under the surface of 200 km is considered to constitute the existence of a salt sea, the Tethys Ocean sandwiched among the ice. With near to Enceladus, and additional large planets satellites, Tethys has also been the role of tidal heating, which makes it beneath the surface of a formation to maintain 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 distant away from Saturn, so by the tidal heating is less momentous. 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 maximum appropriate pedestal as a future where mankind.
7 Ge Lisi 581d
Ge Lisi 581d namely a labeled Geli Si 581 in the Libra star orbit a planet, It namely also found beyond the solar system 1 of the few Earth-sized planets quite one. Gliese 581d location is very favorable to the subsistence of liquid water, so there could be life. Because of its surface is likely covered with deep water, it also became the 1st
Milky Way may be the maximum foreigner of the 7 pl
