As Solar Cycle 25 is reaching its maximum phase, we are witnessing a variety of activity phenomena, including large solar flares and powerful coronal mass ejections, some of which are potentially damaging to our terrestrial environment. While cutting-edge solar observations are now regularly obtained from ground-based observatories such as DKIST, a new space-borne solar observing network is also being established, including the Solar Orbiter and Parker Solar Probe explorers, as well as the recently launched CHASE, ASO-S, and Adytia-L1 missions. Moreover, exciting new space observatories, including MUSE and SOLAR-C, are only a few years away. Progress is also being made in state-of-the-art numerical modeling that is essential for disentangling complex observations and for gaining fresh insights into the highly dynamic nature of solar and solar-wind magnetism and fluid/particle motions. To share and discuss recent advancements in solar physics and related fields, we invite contributions from solar researchers, and also from researchers in heliospheric, planetary, and stellar physics, covering results from their latest observation, numerical modeling, and experimental investigations.
