[QUOTE="Channel Hopper, post: 44848, member: 175144"] Back on Topic Scientists now believe they have the first visual evidence of a planet outside the solar system Using multi position / multi-image cancellation techniques, the first detail of an object orbiting a star approximately 50 light years away has been out onto an image. Some work is still ongoing to ensure the astronomers have not inadvertently captured a distant galaxy instead of a gaseous planet orbiting the white dwarf star. Incidentally more and more data from the Hubble is suggesting that the most likely scenario of any system outside our own, is with two or more stars influencing planet formation. The more common suggestion is that these stars come together by natural movement within a galaxy, and gravitational contact with each other pulls out material in a rotational disc that eventually forms the other objects. The less common view , but one that is gaining popularity, is the existing disc of material around one particular star is 'shepherded' into lumps of rock and gas by the second star, which become planets in their own right. The orbits and gravitational effects of binary star formation is childs play when the effects of a triple system are checked, however most astronomers agree that a single star system with planets in stable orbits is now the exception rather than the rule. Life as we have on Earth is going to be rather difficult to find elsewhere in the Universe [url]http://www.space.com/scienceastronomy/mystery_monday_040510.html[/url] [/QUOTE]
