NASA Kepler snaps evidence of 100 billion Earth-like planets

A new study by astronomers working with the Kepler Space Telescope suggests that our galaxy contains at least 100 billion alien planets.
“It’s a staggering number, if you think about it,” says lead author Jonathan Swift of California Institute of Technology in Pasadena, California. “Basically there’s one of these planets per star.”
Swift’s team has been observing a five-planet system dubbed Kepler-32 that lies about 915 light-years from Earth. NASA’s Kepler Telescope detected the alien exoplanets by flagging tiny reductions in brightness when the bodies crossed their system’s star.
