For the last month, the Cool Worlds Lab has been working hard to finish our analysis of space-based data to solve whether the recently discovered exoplanet, Proxima b, transits its parent star or not. Prof Kipping explains the roller-coaster of emotions in trying to solve this mystery and reveals the final answer. ::More about this Video:: ► Kipping et al.
