Did you know that it wasn't until the 1990s that scientists could be sure there were planets beyond our solar system? Since then, astronomers have discovered thousands of these planets – known as "exoplanets" – circling distant stars. Josh Winn, Princeton professor and author of "The Little Book of Exoplanets," will explain why it took so long to find them, what new technologies and techniques were required, and what kinds of planets have been found. Recent advances have revealed bizarre new planets unlike anything in the solar system, while also bringing us to the threshold of finding other planets similar to Earth.
