First, I have to say you're one of my favourite contributors to the various astronomy documentaries.

My question is, how much of the material you present is scripted by the producers/someone else and how much of it is your own words/analogies and do you write content for other presenters or contribute to their bits? Or worded differently, how much of the content do presenters contribute themselves versus presenting content written by others?

The reason I ask, the content of multi-presenter documentaries is always so consistent and I've always wondered if everything is pre-set or if the producers are just like "talk about tectonic activity on Mars. And go!"

Thanks for doing this and for what you do in general.

I am curious for each of you what is your favourite astronomical object (favourite galaxy, or nebula, etc) and why? If you don't have a favourite object, do you have a favourite Hubble image?
