This event features a talk focusing on the most extreme objects in the universe, such as supernovae, which release significant amounts of energy in incredibly short timescales. The exploration of these phenomena provides insights into the limits of gravity, matter, and magnetism - processes that cannot be replicated on Earth. Conducted by Prof. Dr. Nanda Rea from the Institute of Space Sciences (ICE-CSIC) and the Institute of Space Studies of Catalonia (IEEC), this discussion promises to give participants a deeper understanding of the universe's mysteries and physical phenomena that push the boundaries of our scientific knowledge.
