According to a report Rocky planets, resembling Earth could be found around most sun like stars in our galaxy, a new research suggests, raising scientists’ hopes that they will someday find extra-terrestrial or at least primitive life beyond our solar system.

Using, NASA’s Spitzer Telescope, Michael Meyer of the University of Arizona discovered that at least 20 percent and possibly up to 60 percent of stars similar to the Sun could potentially have rocky planets in orbit around them.

In a report in BBC Helen Briggs said there may also be hundreds of undiscovered worlds in outer parts of our Solar System, astronomers believe.

Future studies of such worlds will radically alter our understanding of how planets are formed, they say.

New findings about planets were presented at the American Association for the Advancement of Science (AAAS) in Boston.
