About the Show
In 1906, astronomer Percival Lowell claimed that the markings he observed on the surface of Mars were canals devised by a drought-ridden civilisation desperately trying to channel water from the planet’s polar ice caps. Though his theory was considered far-fetched, the questions at the heart of it have consumed mankind for eons: are we alone in the universe? Can the barren, icy or fiery worlds beyond our planet support life and, if so, what kind? But the essential question whether or not there is life elsewhere can only be proven if we find life itself. The means to do this is now possible – within our solar system. Mars still dominates our quest and the current Mars missions are actively looking for signs of life on our arid neighbour. But there are worlds beyond Mars that may also harbour life.
