YouTube Description

as posted by the channel

Transits. We all love them. Right now, we know of over four thousand exoplanets which transit their star and these transits teach us a lot about distant worlds. NASA's TESS mission is just getting started, looking to find even more transits! But TESS has a problem when it comes to long-period planets, because it only looks at most fields for a month - meaning sometimes it will see just a single transit of a planet. This makes it very tricky to determine the period and all sorts of biases affect our inference, as we explore in today's video!
