This volume features the proceedings of an international conference held in June 2007 on Santorini Island, Greece, on the occasion of the 15th anniversary of the discovery of the first extrasolar planets around the radio pulsar PSR 1257+12.
The main scientific themes of the meeting included the detection and characterization of earth-like planets (using all presently available and future techniques), planets in extreme environments (dense star clusters, binaries), planets around evolved stars (giants, white dwarfs, pulsars), and the habitability of extreme planets.
