| 16 | KHAG L | No. 136 - APRIL 2025 to the public, the event attracted over 800 registered visitors, including school groups, parents, and well-wishers. Structured around ten thematic groups, the exhibition traced the evolution of Physics from early natural philosophy to modern cosmology. Each group, led by a third-year B.Sc. student and supported by juniors, promoted peer learning and teamwork. The themes included the contributions of thinkers like Copernicus, Aryabhatta, Maxwell, Tesla, Curie, Bohr, Schr ц dinger, Heisenberg, Raman, Hawking, Chandrasekhar, Hubble, and Rubin, highlighting breakthroughs in fields like electromagnetism, quantum theory, nuclear physics, cosmology, and dark matter. Around sixty undergraduate students participated, creating posters, models, and demonstrations—many handmade—including a heliocentric model, Tesla coil, double slit experiment, atomic models, Raman spectrograph, and galactic rotation visuals. The exhibition not only engaged a wide audience but also provided students with hands-on expe r i ence i n sc i ence commun i cat i on , teamwor k , event management, and public engagement. It fostered a deeper understanding of physics and inspired curiosity in both participants and visitors. Tenth Southern Regional Astronomy Meeting: Astronomy Research – Opportunities and Challenges The Tenth Southern Regional Astronomy Meeting, titled Astronomy Research: Opportunities and Challenges , was held fromJanuary 31 to February 2, 2025, at the Department of Physics, Cochin University of Science and Technology (CUSAT), Kochi, Kerala. The event has become a significant platform for researchers in southern India to connect, share ideas, and present their work, fostering collaboration within the regional astronomy community. The meetingwas inaugurated by Junaid Bushiri (Vice-Chancellor, Cochin University). The welcome address was delivered by Aldrin Antony (Head, Department of Physics), and the vote of thanks was proposed by Charles Jose, one of themeeting coordinators. Over the course of three days, forty-three researchers and nine faculty members presented their work on diverse topics, including observational astronomy (planets, stars, the intergalactic medium, and galaxies), active galactic nuclei, the Sun and the solar system, exoplanets, dark matter, relativistic astrophysics, and cosmology. The program featured three plenary lectures delivered by Ajit Kembhavi (IUCAA), Ishwar Chandra (NCRA), and A. N. Ramaprakash (IUCAA). The sessions were
