Life is to be found where there is an asteroid belt


Rebecca Martin of the University of Colorado at Boulder, and Mario Livio of the Space Telescope Science Institute in Baltimore, developed a rather wasteful theory suggests that, for the formation of life on Earth in the solar system should positively be an asteroid belt, and stringently, where it is now.

Observations exoplanetary systems show that the so-called warm dust, which, apparently, the result of asteroid is concentrated in areas close to the "snow line."
