"Is there life on Mars, or anywhere else in the Universe except Earth?”

The Universe is vast and composed of billions of galaxies, each of which contains trillions of stars and uncountable numbers of planets. It seems inevitable that there must be life elsewhere, and yet we have no evidence. The skies are not full of robot probes from other civilizations, nor have our radio telescopes detected the slightest bleep from aliens. The great physicist Fermi put it this way: “Where is everyone?” Part of the reason many people assume that there must be life elsewhere is that they do not understand quite how unlikely the origin of intelligent life on Earth has been. By exploring the only form of life we know – that found here – it begins to look as though we may be alone, in our galaxy at least.

Matthew Cobb is Professor of Zoology at the University of Manchester. As well as studying how maggots smell, he writes popular science books, most recently Life’s Greatest Secret - The Race to Crack the Genetic Code. In 2020 he will publish The Mind Machine: Our Quest to Understand the Brain.
