The moon isn't just a pretty orb hanging in the sky.

It's actually been deeply influential throughout human history.

It helps us tell time, drives us to pursue science, inspires religious thoughts, and much more.

This is Cosmos Quickly, and I'm Clara Moskowitz.

Here to tell us all about how special the moon is, is Rebecca Boyle, author of the new

book Our Moon, How Earth's Celestial Companion transformed the planet, guided evolution,

and made us who we are. Out January 16th from Random House.

Hi, Becky. Thanks for being here. Thanks for having me. So this book is really fascinating and

covers a broad range of topics. Tell me a little bit more about the main idea behind the book and what

you're trying to get across. Well, I've always loved the moon

personally, and it's kind of interesting when I write about astronomy, it's sort of this

forgotten object, and if anything, it's annoying for professional astronomers, because it's so bright,

you have to do sort of deep sky astronomy when it's not in the sky. And I always kind of felt a little bit

defensive about it. Like the moon is worth looking at. The moon is fun. And that's kind of what led me

to this book. It turns out that the science of the moon's formation is actually very heated and

very dynamic right now. One of the inspirations for this book was looking at how the moon came to be.

And it turns out that that story is a lot more complicated than we thought it was.
