A strong cast, episode 557, Red Dwarfs, Friends, or Fos.

Welcome to Astronomy Cast, a weekly facts-based journey through the cosmos, where we help you

understand not only what we know, but how we know what we know.

I'm Fraser Kane, publisher of University Day with me as always.

Dr. Pamela Gay, Senior Scientist for the Planetary Science Institute, and the Director

of CosmoQuest.

Hey Pamela, how are you doing?

I'm doing well.

How are you doing, Fraser?

I'm doing great.

This is, I'm really excited about this topic.

But before we did, I just want to give a huge congratulations again to you and all the

How did anybody get all that done?

I, it, yeah, I think I've mentioned this before.

We all have been traumatized by the rocks, and I found out while traveling with a couple

someone responds, F Bennu, and someone else is like so many rocks.
