I'm pretty sure there are already Exobiologists


Perhaps one of them could put forth a list of the conditions and their parametric ranges for the evolution of intelligent life to be contemporaneous with us in terms of electronic transmissions.

Nice new page on the site listing KOI planets (Kepler Objects of Interest),
giving easy to view size and temperature comparisons :)

http://phl.upr.edu/projects/habitable-exoplanets-catalog/media/kepler


One or two seem very earthlike when comparing mass and temperature,and i'm
sure they will be investigated more thoroughly in the future.

edit : I forgot to mention that these are only candidates and are yet to be fully
confirmed as exoplanets,but I would bet they are 99% sure(as they have been
publicly disclosed)

A small P.S to my above post,

These(although unconfirmed) planets are all "rocky" earthlike planets,
so the chaances of them being brown/red dwarfs,or small binary stars
are very slim.
Those green ones are in what we consider to be the habitable zone,and could therefore have liquid water on or just below their surface.
They are at this moment in time the only places outside our solar system,
where life (as we understand it) can posibly exist, although life beyond
our existing parameters for survival could theoretically exist elsewhere.

using my new found skill of turning words blue on the message boards

voila !! http://phl.upr.edu/projects/habitable-exoplanets-catalog/list_esi

it will still take you to the same site as the first post ,but it's a bit
easier.

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.

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.

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 . :)

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.

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.

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.
