In this latest episode of Book of Nature (Recorded in mid-December, 2018) the Book of Nature trio discuss Comets, the “dirty snowballs” that are our periodically-visiting Solar System Neighbors.  Among our topics in this episode are:

Comets as portents of doom, or as signs of blessings

Our personal experiences with recent comets

The orbital characteristics of comets, and their physical makeup

Space probes launched to explore comets

Bad sci-fi (again?)

and much more.

Listen, here!
