We are pleased to announce the GrandMagnet 2026 international Workshop: Decoding the Magnetized Dusty Universe, which will take place on November 2–6, 2026, on Jeju Island, South Korea. 

The workshop will bring together domestic and international collaborators from our Gravity and Magnetism in Cosmic Ecosystems (GrandMagnet) project, along with the broader research community, to share recent advances, strengthen existing collaborations, and explore opportunities for new ones. The scientific program will cover cosmic dust, astrophysical polarization, and magnetic fields across diverse environments, from the interstellar medium, star and planet formation, and stellar feedback to the Galactic Center and galaxies. The workshop will also highlight advances in theory, simulations, observations, three-dimensional magnetic-field measurements, and future facilities.
