We’re polluting every corner of our own planet, so it only makes sense that we’ll take our trashy habits out into space with us. This week we look at the myriad of ways we’re messing up space, from the trash orbiting the planet to the radiation we’re leaking out into space.

Ep. 81: Questions on the Shape, Size and Centre of the Universe
As predicted we got a lot of questions from people about our trilogy of shows on the size, shape and centre of the universe. Today we’ll do our best to clear them all up.As always, if you’re still confused drop us an email to info@astronomycast.com
Ep. 80: Craters
Pamela’s attending the 39th Lunar and Planetary Sciences Conference, and you know what that means: the Moon… and planets! When you think of the Moon, you think of craters. In fact, that’s a big theme this week at the conference, so Pamela took it as inspiration. Here you go, the week we drove the show into a crater. Wait… there’s got to be a better way to describe this.
Ep. 79: How Big is the Universe?
We’re ready to complete our trilogy of discovery about the universe. We’ve learned that it has no center; rather everywhere is its center and nowhere. We discovered that the universe seems to be flat. It’s not open, it’s not closed, it’s flat. If that doesn’t make any sense, you need to listen to the previous show because there’s no way I could give that an explanation.
So now we want to know: How big is it? Does it go on forever or is it finite in scale? How much of it can we see?
