The Unsolved Universe: Challenges for the Future

The Joint European and National Astronomical Meeting (JENAM) of 2002, was held in Porto - Portugal (2-7 September 2002), corresponding to the I ph Meeting of the European Astronomical Society (EAS) and the IJ! En contra Nacional de Astronomia e Astroftsica (12ENAA) of the Sociedade Portuguesa de Astronomia (SPA). Portugal has a small and young community of researchers in Astronomy. This meeting have had an important role in marking the beginning of what we expect to be a new phase for Astronomy in Portugal. The fact that we have chosen to address '"the future" reflects this will of the Portuguese com munity to share and discuss our commitment for the next decades with our colleagues. The meeting, titled "The Unsolved Universe: Challenges for the Fu ture", aimed at discussing some of the major research programmes and objec tives for the next decades. The scientific programme included the plenary ses sions (invited reviews and highlight talks), whose contributions are published in this book, and several workshops on more specific topics.
