- Leading scientists and researchers weigh in on the scenarios that might unfold if aliens find us and decide to visit Earth. Should we even be searching for extraterrestrial life? What are the risks of reaching out, and what are the risks if the Earth is "found" by aliens?.
- Just for a moment, imagine a universe awash with life, where we humans are not the only intelligent beings around. What might these alien races look like? Could we communicate with them, or even recognise them as intelligent? And what would they make of our violent and dangerous species? Might they take one look, and decide not to bother with such primitive beings? A planetary nursery filled with spiteful, galactic infants. On the other hand, in our imaginary scenario, they may enrich us with scientific knowledge beyond our imagination. Or could an encounter with aliens have a more destructive outcome? It could be a bad day for human kind. But relax, it's just make believe, it could never happen, could it?

Join the search for extra-terrestrials and hear from scientists who think we are on the verge of making contact.
