The inner solar system

You'd think that we'd know everything there is to know about our neighbouring planets, but there are many mysteries still out there.

Why does Mercury have such a huge iron core?

Is there life in the clouds of Venus?

Are we all Martians?

We don't expect to be able to answer all these questions in one evening, but do come along as we have a go. In the process we'll probably end up with even more questions!
