This week's episode of Astronomy Cast is sponsored by Barkbox. I've said it before and I'm going to

say it again. We are super lucky to have sponsors that are also companies we just plain love.

I was a Barkbox subscriber before we got this sponsorship and I'm going to stay one for a long time

because Eddie, my big old Australian shepherd, loves Barkbox. If you don't follow me on Twitter,

you may not have seen this, but I've been putting out unboxing videos because he knows when the box

is from Barkbox. This is partially because it has four to six natural treats inside of it and he

kind of wants his treats. It's also because it's like always the same size box and he wants the box

and it's gotten to the point that he goes in. Now first, I don't even have a chance to like completely

get the lid open before he's in there and he's pulling out first one soft squishy toy and then

the other soft squishy toy and he's playing for a few minutes and then he's like mom, it's time

for a treat. So if you want to give your dog this kind of amazing treat once per month, go ahead and

do like I did and subscribe to a six or 12 month plan at Barkbox and in fact, you will get a

free extra month from Barkbox if you visit barkbox.com slash astronomy and subscribe to a six or

12 month plan. So go get yourself a happy dog. Thanks.

Great survey survey. Okay, so as we mentioned in the last episode, we have been hosted forever by

which I mean for like 10 years, almost 11 years on a Lipson media and they've taken care of us and

they've asked if we could ask you to do a survey. And since they've been so good to us, please,
