Thanks for that snug
Carl Sagan is a bit of a hero of mine, and I really became interested in Astronomy after seeing his 8-part series called "Cosmos" which he put out in the early 80's (or thereabouts). If you can get hold of it, do yourself a favour and do so. I'm in the middle of watching it all again right now - twenty-something years later and it's just as good now as it was then. CGI has come a long way, but what the hey - it's the subject matter that counts
