Understanding how unusual Earth is may help humanity to appreciate how special it is.

November 2016: More than 3300 planets are known to orbit stars far beyond the solar system, in planetary systems very different to our own. There may well be hundreds of billions of extrasolar planets in the Milky Way alone. These planets include planetary types not found among the eight planets that orbit our Sun, including mini-Neptunes, super-Earths, rogue or nomad planets and hot gas-giant planets. Are we therefore alone in the Universe? To answer this pertinent question, we seek to understand the formation and evolution of our own solar system and the reasons for this rich planetary diversity.

The Centre for Exoplanet Science brings together researchers from different disciplines to find out how planets form in different galactic environments, how their atmospheres evolve, and the relation between the evolutionary history of planets and the emergence of life. We are further interested in the moral, ethical and technical aspects of detecting existent or extinct extra-terrestrial life in distant exosystems, or within our own solar system, and the significance of such a discovery for our societies.

The Centre for Exoplanet Science builds on the rich legacy of the SUPA Astrobiology initiative.

The Centre for Exoplanet Science currently combines research from the School of Physics & Astronomy, the School of Earth and Environmental Sciences, and the Department of Philosophy at the University of St Andrews.

We are affiliated with the   Centre for Exoplanet Science   at the University of Edinburgh.
