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."
This may be because it was her form giant planets; the light elements are not
able to condense on the surface of a celestial body, whether it is closer to
the Sun.
