"NASA's Spitzer Space Telescope has revealed the first known system of seven Earth-size planets around a single star. Three of these planets are firmly located in the habitable zone, the area around the parent star where a rocky planet is most likely to have liquid water."

It's about 40 light years away though
That's a hop, skip, and a jump. No problem for my HFT.*
Keep in mind that being in the habitable zone is just one of many requirements for advanced life to potentially exist. Earth, in addition to being in the habitable zone, has a near circular orbit around sun, a stabilizing, life-supporting moon, and a protective Jupiter. Also, earth is not tidally locked to the sun -- which is the case with many cooler stars and their planets that are in the habitable zone.

I read that if a planet has a thick enough atmosphere it can help distribute the temperature even if tidally lock. Is there any truth to that claim?

Computer simulations say that is possible.
