In the last thirty years humans have probed the Universe, explored the
Solar System and visited with spacecraft some of the most incredible
places humans have ever laid eyes upon. We have expanded our knowledge
slowly and surely, but still now only see a glimpse of the bigger
picture. The Cosmic Keyhole explores the big discoveries of recent years
and asks what's next? How prolific is life in the Universe? How far back
to the Big Bang can we probe? And what hidden treasures still await us
in the hidden corners of our Solar System?
