This month’s Astronomy is a special issue about exoplanets.
Astronomers have discovered about 200 planets outside of our solar system. What do these distant bodies tell us about planet formation? How soon will we find an exoplanet that is earthlike? Have we found any exoplanets that appear habitable? How will the hunt for other worlds change in the coming years?
Senior Editor Rich Talcott provides the ABCs of exoplanets in the week’s podcast.
