Comment on Kepler-22b by Alpha-Element
Awesome. If they found 1 or 2 planets like this within the Kepler spacecraft's field of vision alone, imagine how many there are in our galaxy! 
thanks, glad you like it!
and your right, kepler can only see the planet's that transit their stars as seen from our system. so if kepler found like 30 transiting habitable planet candidates within a narrow field of view stretching maybe 3000 light years, theres no telling just how many habitable worlds there are out there in our galaxy alone!

You're welcome ^-^
At least 1000!
At least 1000!
at least 1000? i say at least 1 million!
Well Kepler is looking at about 145,000 stars.
It has found about 30 candidates for planets that may support life.
There are about 200,000,000,000 stars in the galaxy.
The following I'll use a calculator for:
200,000,000,000 divided by 145,000 equals 1,379,310.34483.
1,379,310.34483 multiplied by 30 equals 41,379,310.3448.
So we're both way off but you're closer.
There should be over 41 million habitable planets in the Milky Way galaxy alone.

actually, there should be even more than that! remember, you only used the number of habitable planet candidates that transit as seen from earth, and not the total number kepler is gazing at could be much much higher! so there could be at least 1 billion in our galaxy alone!
So for every 200 stars there is a habitable planet. That means that there would almost certainly be life in more than one place.
yeah, most likely!
