Exoplanets: Are There Other Earths? Be Smart
We live in one of a hundred billion of galaxies, each with hundreds of billions of stars. And now, thanks to modern astronomy, we know that the Milky Way is home to perhaps a hundred billion planets! In the past two decades, these exoplanet discoveries have spawned new questions about our universe, and if there might be another Earth, or other life, somewhere out there.
