Welcome to Astronomy Cast, a weekly facts-based journey through the cosmos

where you help you understand not only what we know, but how we know what we know.

I'm Fraser Kane, publisher of Universe Today, with me as always,

Dr. Pamela gave the director of Cosmo Cross. Hey Pamela, how you doing?

I am doing well. How are you doing, Fraser?

Great. Hello from TwitchCon in San Jose.

I hope you have a great time there. Before we get any further, I just want to say,

by the way, last week I said it was about to happen. Now it has actually happened.

Our book has hit the shelves. October 23rd came and went, and now you can just go to a bookstore

and buy a copy of her book. Many of you I know ordered copies of it.

The sort of first versions, people are loving how it looks, all the photography,

but nobody is reviewing it on Amazon. So we are the top-selling book.

It's a weirdest thing. We're the top-selling book in astronomy and astrophysics on Amazon.

Take that Neil deGrasse Tyson, but there's like no reviews of the book.

So if you've ordered a copy and you've got a copy in your hands, please take a moment and

go to Barnes and Noble Amazon. Wherever you bought the book from, and please write a review.

It's so weird to me. I don't know. Did we do a good job?
