The IAU Symposium 410 “New Look at Solar and Stellar Coronae” will tackle some of the most pressing open questions in coronal physics, capitalizing on the rapid expansion of high-resolution solar and stellar observations and the growing synergy between solar and stellar research communities. Scheduled for 22–27 November 2026 in Shenzhen, China, the symposium coincides with the arrival of major new facilities and missions, as well as significant theoretical advances, making it an ideal moment to reassess the fundamental physical processes operating across the Sun and cool stars. The program spans impulsive phenomena, such as solar and stellar flares and CMEs, coronal heating and winds, coronal seismology, atmospheric connectivity, etc., alongside novel data-analysis and diagnostics approaches, laying the groundwork for effective exploitation of the solar–stellar analogy. The official symposium website will be released soon; in the meantime, you can access the description of the event here: https://www.iau.org/Iau/Science/Scientific-Meetings/IAUM2026/IAUS410.aspx
