Astronomy from the Moon: From Exoplanets to Cosmology in Visible Light

I look at what astronomy from the Moon might be like in the visible over the next few decades.The Moon offers the possibility of installing large telescopes or interferometers with instruments larger than those on orbiting telescopes. I first present examples of ambitious science cases, in particular ideas that cannot be implemented from Earth. I discuss also the issues which I telescope will encounter underlunar conditions. After a general review of observational approaches, from photometry to high contrast and high angular resolution imaging, I propose as a first step a 1-metre-class precursor and explore what science can be done with it.
