NASA discovers most Earth-like planet yet

The Kepler space telescope has once again identified a promising Earth-like world around a distant star.
The newly discovered planet is only 1.5 times the diameter of the Earth and orbits in the habitable zone, the region in which the temperature is sufficient to allow liquid water to exist on the surface. The planet takes 242 days to orbit its star and is a bit closer to it than the Sun is to the Earth.

"It's a big deal," said astrophysicist Mario Livio. "It's definitely a good candidate for life." Kepler astronomer Natalie Batalha was also enthusiastic about the discovery. "This was very exciting because it's our fist habitable-zone super Earth around a sun-type star," she said.
A possible alien planet discovered by NASA's Kepler space telescope is the most Earth-like world yet detected beyond our solar system, scientists say.

Whats the next step ?. Are we going to aim our radio waves at it in the hope of a reply. Has anyone said how far away it is ?

The star KOI 172 is about 1040 light years from Earth. If there is intelligent life on the prospective planet, it will almost certainly be due to colonization from another star system. KOI 172 is thought to be only about 400 million years old. This is very probably too young for it to have evolved intelligent life of its own. If nothing else, it might host a geological survey settlement. Such a young world might be of unusual interest to ET scientists.

*SNIP*that is a interesting discovery and planet as well.the question is can we take care of it though?meaning are we going to learn from our mistakes and take care of the planet good or mistreat it.because in my opionion yes we could find planets to live on but if were going to pollute it and mistreat meaning digging up oil and etc and repeat the sames mistakes we are doing on earth then we havent learned anything at all as a living species

Perhaps fortunate, in at least one respect, then, that a planet 1000 light years away, or even 10, is apparently going to be beyond our reach for quite some time to come. Perhaps by the time we've learned, or been taught, how to travel the stars, we will have acquired some additional wisdom.

Whatever it takes to extend our species, in my opinion. I guess if that is the case, but then maybe other species from other planets might be thinking the same thing. What if we arrived there the natives were not exactly friendly but decide we make good food. I am sure they will seek out the planet of our origin to conquer it themselves so THEY may extend their species. It is not all cut and dried.

Just a reminder, there's a forum for conspiracy discussion. This is the science and space forum, please stick to scientific discussion.

Interesting question, then, maybe: The galaxy is about three times as old as our little planet. Why hasn't someone else colonized us? Maybe the galaxy is a more civilized, lawful place than we realize. Or we are not worth the effort

how fast or better question is when can humanity start colonizing it?and any other earth like planet?that would be so awsome and cool though.start colonizing other planets already.

how fast or better question is when can humanity start colonizing it? This planet is over 1040 light years away. The fastest spacecraft mankind has so far launched would take more than 4.7 million years to arrive there, so I think colonisation is out of the question for sometime to come.
