kepler 22b - Life or Gas?

ToxicTrevor:
I'm sure some of you have heard of the planet 600 light years away known as Kepler 22b, if not allow me to provide
a short summary so you may also be educated on the topic. Kepler 22b was founded to be in existence on December 5Th, 2011, its radius is roughly 2.4 times the radius of our home planet earth, its mass and surface composition are unknown, its also determined to have a 290 day cycle per year. With such little inconclusive data the arguments arisen are all theory, some claim it could be "ocean-like" while some scientist speculate it's mainly gas. The distance from its host star shows evidence that it is NOT subject to extreme temperature changes, if the atmosphere provides a greenhouse effect similar in magnitude to the one on Earth ( which is still inconclusive. ), the planet would have an average surface temperature of 22 °C (72°F) habitable by life. NASA scientist have referred to its placing in the 'Habitable zone' or the 'Goldilock zone' as some evidence that life could in fact be sustained.

With all of this being throw in your face, what is your opinion? Could Kepler 22-b hold life? Does it hold life now? Is it just a 'Super-Venus' full of gas? state what you think.

pacmn:
Any planet could hold life. This is just one that's more appealing to us because it seems more like our planet.

IAMFORTE:
This sort of question can't really be answerd without more research, even then, opinions would be pretty much reduced to the level of speculation and gut feelings, If theres life on that planet, does it matter? Not in the slightest? The planets way to far away for it to ever have an effect on mankind (other than a small novelty and the discovery that we are not alone in the universe) which can be pretty much deduced with more gut feelings to begin with.

That's what I'm asking to hear, without hard evidence people are forced to answer based on personal feeling as there is no right or wrong answer, however there opinions can be supported by facts from other things.

We won't be able to find out for a long time. The instruments we have right now can't do any precision studies of something that far away, and to send a satellite would take over 600 years. If you're basically asking "Hey, do you think there's aliens out there somewhere?" sure, I think there are, but I don't think we'll see them in this lifetime.
