The 2nd PANDA Symposium aims to include experts in many of these areas. Like the first of its series it is organized in 4 days: the first day will have lectures from senior lecturers setting the stage on the subject matter with comprehensive reviews. The next three days are organized as independent mini-workshops in three scientific sub-areas. During these workshops, graduate students and young post-doctoral fellows will present their results on ongoing projects to their peers. A major goal of the PANDA series is to enable scientific and cultural interactions and mentoring across the international borders. The first meeting was very successful, with the students expressing their strong desire for the next such endeavor. We have formed a scientific board comprising members from the broad international astrophysics community, which has provided guidance on the organization of the 2nd PANDA Symposium.
