using my new found skill of turning words blue on the message boards Thanks john3760 for the link above. I love me some exoplanets BIG TIME. I am new to the SETI@home project and this fine community you guys & gals have here. I feel Blessed to be part with all of you in the search for E.T. If you want it, get it. If you dream it, believe it. The sky's never the limit. So go on, show the world who you are. Don't be afraid to show your true colors. |

Welcome to SETI@home. There are a couple of links on this thread to Exoplanet sites,one of which (planethunters) involves actually searching for exoplanets yourself,using Kepler telescope data.You might find that one interesting. Einstein@home searches for radio pulsars (stars). As I stumble upon other Exoplanet websites I will post links to them here on this thread, and if anybody else knows of good sites please post links here as well. john3760 |

Good find, John. Looks like I'll have to add this one to my favorites! |

Here's a link to the Kepler home page,on NASA's site. http://kepler.nasa.gov/ Full of facts about the mission,and all confirmed exoplanets,as well as KOI's ( unconfirmed exoplanets). Plus all the very latest news . :) john3760 |

Anothe nice little piece ,from National Geographic. http://ngm.nationalgeographic.com/2009/12/new-earth/planets-animation It shows the relative sizes of known Exoplanets up to the date of the article. john3760 |

Thanks Lynn. More up to the minute news from Science Daily. Here's a link to their Exopanet section. http://www.google.co.uk/url?sa=t&rct=j&q=exoplanet%20newspaper&source=web&cd=1&ved=0CCkQFjAA&url=http%3A%2F%2Fwww.sciencedaily.com%2Fnews%2Fspace_time%2Fextrasolar_planets%2F&ei=tkSbT4awHM7J8gPF5bGADw&usg=AFQjCNGcqQGUxqLYxUrYXaWobDwc55uvwg&sig2=aMZDqT6KHQyxYrqMCnoJcw john3760 |

News,from somebody's point of view. I totally agree with them :) http://www.abc.net.au/science/articles/2012/04/27/3490608.htm?site=science&topic=latest john3760 |

I only wish out of the closest stars a habital planet existed not a one is closer than 5 lightyears that an impossible distance for us to travel. We have to find a stable world within a few billion years. with mans waring attitude we might not be around to care. None of these worlds is a earthlike planets and the one mentioned is 4.5 times the size of earth. Astonauts traveling that far probally couldnt stand up in that gravity. A 200 pound man would weigh a ton on its surface. |

Just take a look at the distances involved at the present time impossible distances to do a random visit. We have to take in to accounts of where these planets are 3 billion years from now when andromada collides with us. Wouldnt want to populate a world and have it in a future impact zone.. |

Impacts among stars are highly unlikely in galactic collisions. Stars are so far apart they are more likely to bounce off each others heliosheath or magnetosphere. In a rich man's house there is no place to spit but his face. Diogenes Of Sinope |

The distances involved to any of the earthlike planets there are 3 one just smaller and two a little larger than the earth. They are so far away. This is what I tell the UFOologists the distance from another star is a tremendous distance even a light year is a great distance. Its taken voyager 1, 34 years to go 11.1 billion miles. If we travel these tremendous distance only to find out the atmosphere is poisonoous. It has oxygen how much?, whats the air pressure. All this study would have to be done somehow before hand. Some of these earthlike planets are 2900 lightyears away. Its amazing just how they are detected so far away. |

Translating Voyager's journey into light wotzit speeds. Overall it has averaged about 0.5 light HOURS per earth year (radio signals take about 17 hours to do the one way trip). That's not allowing for its meanderings around the solar systems, taking those into consideration maybe its approaching one light hour per Earth year. And who knows what is going to happen to its velocity in the next few years as it performs the break out from the Solar system into inter-stellar space. And how far away is our nearest neighbour - something like 3 or 4 light years, in other words substantially more than my life time at Voyager's speed.

Caution. I doubt they are "Earth Like" . Perhaps they share one parameter in the right range out of maybe 20 that makes our Earth habitable at all for intelligent life to start and evolve. |

Assuming a habitat has to be Earth-like for intelligent life to evolve... I dunno about that. Extremophiles evolve. I think given enough time, any life in almost any environment could evolve to intelligence. #resist |

I assume by Earthlike, they just mean it has the same ( or similar ) mass,with a temperature allowing liquid water to exist. Beyond that nothing is certain. The star which the "Earthlike planet" is orbiting may be so different from the sun that life could not exist,or many other parameters could be so different from our own planet. Rocky planet,with the possibility of liquid water,about the same size as Earth,is the best hope we have ,as we know life exists on a planet just like that. Ours ! john3760 |

I'll bet that if we tried and were sufficiently knowledgeable, we would find about 2 dozen factors and their parameter ranges that are required for the emergence of intelligent life that we could communicate with. To start with they would have to be close to us. I have listed several elsewhere that I feel are required. Can you all point to some of these and others. Temp range, stable orbit, circular orbit, moon to stabilize spin, Tides ?, water, land, Oxygen, outer gas giant to protect from asteroid and comet hits, magnetic field, ozone layer, several billion years old, main sequence star, non-binary star, etc |

Has anyone stopped to think that if we find a planet at long range that appears to be suitable for life such a planet probably has it's own biosphere complete with life and possibly even if no communication via radio or other electronic means, intelligent life? If such a place is found my feeling is that they should be left to their own devices and not interfered with in any way. Maybe my feelings are strongly influenced by Star Trek's prime directive and the events depicted in the movie "Avatar" but that doesn't make them any less correct.
