What have we learnt about the formation of stars and planets by imaging young stars, and in particular the circumstelllar discs of material around them? Can you grow a star by accreting from a disc? How quickly does the material in the disc get converted into planets? Can we understand what causes the outburst events on young stars? Can we detect young planets directly? How does this relate to the formation of our own solar system? I will try to answer all of these questions, and more, in just 45 minutes of your life.
