Alan Boss: I think we're on the verge of finding out just how many Earth-like planets there are in the universe.

You're listening to astronomer Alan Boss. He's hoping to get more answers about Earth-like planets from NASA's Kepler Mission, launched in March of 2009. [---1---]

Alan Boss: [---2---]

Boss said the universe could be crowded with rocky planets like Earth — some possibly with water, and even life.

Alan Boss: [---3---]

Boss bases his hunch on the fact that for nearby sun-like stars, about a third have turned up what are called 'super-Earths', planets five to ten times more massive than Earth.

Alan Boss: [---4---]

As we look up to the night sky, said Bass, nearly every star we see might have an Earth-like world, 100 billion in our galaxy alone. His new book is called The Crowded Universe.
