Kepler's data will be released in february. Perhaps proof of extrasolar life are in ?

>> No.1388196

just because you can find other planets of similar size and with similar conditions does not mean that life exists there.

>> No.1388206

>>1388186
Short of them finding a Klemperer rosette, the Kepler isn't going to find evidence for extrasolar life. Kepler can find planets that are in the habitability zone, but that does not guarantee that there is life there.

>> No.1388215

the only good thing out of this is that if we find a planet that's very similar to earth we can migrate there once we get the technology to do that

>> No.1388231

Ok, I make a mistake, not IN data, but data will permit to identify an earthlike planet we will study to find proofs of life...

I'm also wondering how religious people would react...

Still the matter of getting there before we can do any real exploration of the presence of life. Getting there is hard.

Don't go there, please.

>> No.1388268

>>1388239
the same as ever. Even when we discover extraterrestrial life they'll still claim god put it there. And even if we are contacted by intelligent beings and they tell us they don't believe in a creator, the religious people will claim they are heretics. Basically no amount of logic or proof will change their beliefs.

>> No.1388286

Speaking as one, excited.

However, as has already been stated, this doesn't prove life is out there. We need a way to reach the planets first.

>> No.1388297

>>1388253
why so hard, we can identify components of the atmosphere like O2 or CH4.... CH4 could be volcanic... I also know that not all detected planets can support atmosphere analysis, but man : 700 worlds !!!

why so ? spectrograph !!!

>> No.1388314

>>1388215
That's not the ONLY good thing from this

Science as unexplored as space requires all the proofs we can get. For all we know, there could be no planets with even atmospheres outside of the Solar system.

By confirming hability potential of both planets (and maybe soon, their atmospheres) we are just making the necessary steps to publicly verifiable evidence which will lead to more educated searches for exosolar life.

>> No.1388316

that's nothing, if you point your telescope in any direction in the night sky then in that little spot there are about 10000 galaxies

>> No.1388324

>>1388297
We can do that at the relatively short ranges we have in the solar system. Doing that with a planet we can't even see isn't really an option. In order to do so we either need a breakthrough in propulsion to fly our instruments closer or a breakthrough in our instruments so they can pick out things at trillions of kilometers

gravity on the moon and mars is very different than earth. Just because you can put a man there does not mean that you'll be able to breed people with that gravity. Already you can see the effects of no gravity on people coming back from the ISS after a 6 month stay, they are very weak and their bones are brittle. I think that the human body will not form under low gravity conditions.

Also there's the problem of radiation, asteroids, supernovas, etc. Space is dangerous as hell, it's just that it's on such a big time scale that we don't notice.

i predict that humanity won't survive the next ice age, that'll be the end of us.
