Every star we see in the sky has at least one planet orbiting it, says astronomer Sara Seager. So what do we know about these exoplanets, and how can we find out more? Seager introduces her favorite set of exoplanets and shows new technology that can help collect information about them — and even help […]

Different species often depend on one another. David Gonzales describes the remarkable relationship of the Clark’s nutcracker and the whitebark pine, to illustrate the interdependency known as symbiosis.
