The search for life elsewhere in our Universe has long been the Holy Grail for astronomers. Planets around distant stars have recently been discovered and we now realise that solar systems like our own could be widespread. So is life on Earth unique? With missions to Mars, Saturn's moon Titan and Jupiter's moon Europa, we could be nearing an answer. No definitive traces of life have been found elsewhere, but astronomers are probing ever deeper on our nearest planetary neighbours and across our Universe for the signitures of life. Patrick Moore discusses the issue with Professor Monica Gardy and Professor Simon Conway Morris.
