Trillions of Earth-like Planets in Universe?
The universe is teaming with trillions of Earth-like planets bearing alien life forms with many harboring possible civilizations thousands of years more advanced than ours says astrophysicist and author Alan P. Boss of the Carnegie Institute in Washington [video].
"I suspect virtually every star when you look up at the night sky has an Earth-like world around it." These "exoplanets" are mainly gas giants like Jupiter but they should include some super-Earths a few times larger than ours," Dr. Boss recently said recently of the more than 340 known planets orbiting neighboring stars with many more expected to be found by the Kepler spacecraft to be launched this year.
