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 (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.

Clouds and hazes have a fundamental impact on the physical structure and appearance of planetary atmospheres and even influence the habitability of earthlike planets. Recent years brought an abundance of data on clouds in exoplanets. In the school we will review physical models for cloud formation in Solar System planets, exoplanet observations, and laboratory studies.
Christiane Helling and Aubrey Zerkle are invited speakers.
