Abstract: Extrasolar planetary systems are very diverse in their properties compared to the solar system. By observing and modelling the discs out of which the planets form, we can attempt to see how this diversity emerges, and start to look into implications such as the frequency of other habitable planets. I will show examples of unexpected phenomena in circumstellar discs, and present methods of high angular resolution astronomy looking at discs on few-AU scales. Our first results are appearing from the Planet Earth Building Blocks Legacy eMERLIN Survey (PEBBLeS), and I will discuss the discovery space of this project, and the future going into the SKA era.
