| 0:00.0 | I love talking about exoplanets, which if you haven't tuned into the latest |
| 0:12.4 | astro jargon yet. |
| 0:14.3 | Exoplanets are planets orbiting other stars. |
| 0:17.2 | They are extra solar planets, hence exoplanets. |
| 0:23.6 | I mean, I'm sure our home solar system has so many cool things going for. There are four giant planets. There are liquid water oceans, |
| 0:28.8 | under frozen icy moons. There's a planet with this giant magnificent ring system. |
| 0:34.0 | Oh yeah, there's that one planet with life on it too. There's lots of cool stuff happening in our own solar system, but I've said this before, |

| 1:08.7 | driving. Close your eyes. Imagine a crazy, complicated, super exotic alien system. |
| 1:17.2 | One, nature already has that. It's real. It exists. |
| 1:21.6 | And two, nature has something even cooler. |
| 1:25.4 | Case in point in the subject of today's episode, the Trappist One system, which is a family |
| 1:31.3 | of planets orbiting a star just about 40 light years away. |
| 1:35.7 | First, I want to talk about the name Trappist One. |
| 1:38.6 | It's original name. |
| 1:40.5 | Trappist One is not the original name for the star 40 light years away. |
