Less than twenty years ago, the Solar System was the only planetary system we knew about. Since then, astronomers have discovered many hundreds of exoplanets - planets that orbit other stars than the Sun.
We now know that exoplanets are common, perhaps even outnumbering the stars in our Galaxy. Some of them are so utterly unlike the Solar System planets that they challenge both our imagination, and our theories of how planets form and evolve.
In this talk, some of the highlights and challenges of exoplanet exploration in the past decade will be described, and outline how we are working to detect and characterize an ever wider range of planets, including some which may harbour life.
Dr Aigrain is from the Department of Astrophysics, University of Oxford.
