0:00.0 | Capturing the entire Cosmos in a book this week on planetary Radio. Radio. Welcome to the Travel Show that takes you to the Final Frontier. |
0:20.0 | I'm at Kaplan of the Planetary Society. Astronomers Alex Philippenko and J. Passikoff have just published the fourth edition of |

0:30.4 | We'll talk with them right after we hear from Emily Lacowala and Bill Nye. |
