Astronomer and BBC Sky at Night co-presenter Chris Lintott used to be annoyed he missed the Apollo era, thanks to failing to be born early enough. Recently, though, he realised this is the golden age of space exploration, but the tools aren't spaceships - they're telescopes and computers. This will be a whistle stop tour of progress in the really big questions that keep astronomers up at night - how the Universe began, what is it made of - and is there anyone out there?
