An international team of astronomers combing through data from the US Kepler space telescope said Tuesday they have discovered a solar system with five Earth-sized planets dating back to the dawn of the galaxy.
Researchers say a few hundred thousand billion free-floating life-bearing Earth-sized planets may exist in the space between stars in the Milky Way.
It may be possible that one in 4 stars similar to the Sun could be orbited by Earth-size planets.
The researchers found larger numbers of smaller planets than of larger planets.
