A detailed account of the major progress accomplished until present was published in Annual Review of Astronomy & Astrophysics (Mirabel & Rodr\'ıguez, 1999). Here I review the questions that remain unanswered, as well as the future perspectives that this new field of research is opening.9 pages, no figures.
