Since the dawn of man, we have looked up at the stars and wondered what was out there. We are just now discovering other worlds beyond our own star! How do we do it? Find out as we dive deep into planet and exoplanet hunting. Exoplanet detection takes very advanced technology. We go over the most successful methods we've used, and some methods we'll be using soon, once we launch some more space telescopes! We go over the history of planet detection, including how we discovered a planet using math!
