Subject: RE: “Perfect planets for life” – in the galactic habitable zone?
Hi [PizzaMan],
Size of a planet and its location around a star are only two out of over a dozen factors that determine whether a planet is habitable. They don’t consider in these news articles whether the system is within the Galactic Habitable Zone. [It means, Sol & Terra are on the outer surface of a galactic arm, in a position that permits both the rise of life and observation of a significant part of intergalactic space, attributes that may not be separate in the greater scheme.]
Best,
G^2

Hello, Professor Gonzalez, thank you for reading my e-mail, it’s a privilege, I have a fan page http://www.sacra-pizza-man.org/privilegedPlanet.html
May I inquire, does the science behind this page http://www.foxnews.com/science/2013/04/18/perfect-planets-for-life-telescope-sees-distant-worlds-not-too-hot-not-too-cold/?intcmp=features include consideration whether or not the described stellar systems are within the galactic habitable zone?
