Irini Roumboglou was brought up on the Greek myths of her homeland, and science fiction television programmes like Star Trek.

This combination has resulted in a fascination for our endless quest to discover life beyond our world and our innate need not to feel alone.

She meets the people who spend their lives analysing and listening to the noise that emanates from space in their search for extraterrestrial intelligence.

As she discovers, there has been a fundamental shift in the way the skies are being scanned for signals and so the possibility of contact from other life forms seems closer than it has ever been before.

Will these optimistic scientists really find voices from other worlds, or will they simply discover that Earth is unique and alone?
