In a study published in the journal Astronomy & Astrophysics, researchers say that they've discovered a solar system with not just one, but three planets that could support life only 22 light-years away from Earth. Rory Barnes, the lead U.S. author of the study, talks about how it's possible to find multiple "Goldilocks planets" around one star.
