so non-terrestrial worlds that leaves out the ovious ISS

http://www.jpl.nasa.gov/history/hires/1967/surveyor3_apollo12.jpg
Name: moon
type: moon
mass size 1:80
info: proven life forms by NASA, A part of the natural habitat of surveyor 3 was left untouched so their probebly some lifeforms left there in hybernation.
original origon however is terrestrial

http://www.space.com/images/060801_cancri_planets_02.jpg
Name: not named found/yet
Type: smaller jovian or terrestrial
mass size:? (??50% earth??)

Unfortunately the Surveyor 3 bacteria find looks like a mistake;

Sight well... I'm glad my taxes aren't lost on NASA. They should have taken their test pilots to a factory and let them make boxes for a month or so, that would have teached them how to bag and tag properly

anyway

name: Zeta Reticuli (star)
type: hypothetical planet
mass: unknown
adress: http://en.wikipedia.org/wiki/Zeta_Reticuli
info: Home of the greys?? (not confirmed)
:) :) :)

Magaret Turnbull and Jill Tarter have produced a magnificent catalogue of 17,129 stars which may be suitable for life; of those stars, Margaret Turnbull has picked 37 Geminorum as a fairly close, good sunlike star
http://seti.astrobio.net/news/print.php?sid=164

Other good sun-like stars nearby include 18 Scorpii, Beta Canum Venaticorum and HD 98618. 51 Pegasi is also sun-like, but is spoiled by the existence of a hot Jupiter-like planet in a close orbit (this planet has been informally named Bellerophon).

Alpha Centauri is even a better candidate I think.

Unfortunately the Surveyor 3 bacteria find looks like a mistake;
http://en.wikipedia.org/wiki/Myth_of_Streptococcus_mitis_on_the_moonHowever from the astrobiology link at the foot of your wikipedia lnk we have this:
The longest exposure time of bacteria to the harsh vacuum of space was a Bacillus strain that was revived after six years in a controlled biological experiment, so even if the Apollo 12 results are questionable, the ability of bacteria to survive extreme environments is not particularly in question.

All is not lost.:)

Perhaps even Proxima centauri, It's theorised that it should have a planet 80% of jupiter, that would get around the same amount of light like the asteroid belt in our solar system. Titan is a prime example that large moons can have a atmosphere. A large Ice moon with methane producing algae, it's a looong shot but not inpossible.

I wonder when they would proof disproof this planet, because it would be the closests exoplanet to earth.

I think it is very possible that soon they will confirm the existance of one or more planets orbiting one of the stars in the Alpha Centauri star system. After that, see your travel agent for special travel deals.

lets be realistic here people.
please follow the format specified.
Thank You.

Well, we are beginning to run out of known candidates. All the extrasolar planets we have found are poor prospects for Earth-like life; we can't speculate with much confidence about life as we don't know it.

But here is another candidate within our own system;
http://upload.wikimedia.org/wikipedia/en/6/61/Enceladus_north.jpg
Enceladus, a smaller version of Europa with a possible sub-ice ocean.

you know...of all the candidates (my 1st post)...Encelados seems the best candidate for presence of life.

what abouth Europa? I would defenitley give that one more changes

what abouth Europa? I would defenitley give that one more changes

Europa sure is a great candidate just as Encelados. Submerged water ocean.
I wonder what the difference between the two is. It seems like Encelados has the thermal vents...but does Europa have it? Anyway, sunlight is not necessary for life, archaea (http://en.wikipedia.org/wiki/Archaea) can exist there.

It's not proven that Europa has any thermal vents at the surface (http://www.solarviews.com/eng/eurpr2.htm), but it has many cracks and many craters are partially refilled generally the surface is also pretty young but that's abouth it. But it's possible that there are (also) subsurface thermal vents but theories get a bid hasy depending on how thick the upper ice layer is, and what exactley lays beneath the somewhat proven liquid salt ocean.
It certainly would deserve a advanst radar mapping mission, but who am I to tell NASA what to do.
