7. Listen again and fill in the gaps:

Interviewer: Is this your first time being in a space documentary?
Scientist: No, I sort of come whenever NASA calls. When someone wants to talk to a NASA … I usually show up. I've done a lot of television before.
Interviewer: You talk about the immense size of the universe. So how big is it?
