Solar telescopes as a research area encompasses the design, optimization, and scientific exploitation of instruments dedicated to high-resolution, multi-wavelength observation of the Sun. This field integrates optical engineering, adaptive optics, polarimetry, spectroscopy, and imaging techniques to measure solar photospheric, chromospheric, and coronal structures and dynamics. Research focuses on improving spatial, temporal, and spectral resolution; mitigating atmospheric seeing; and extending observations from radio to gamma-ray regimes, including space-based and ground-based platforms. It supports quantitative studies of solar magnetism, flares, coronal mass ejections, and irradiance variability, providing critical data for heliophysics, plasma astrophysics, and space weather forecasting.
A research team from the Yunnan Observatories of the Chinese Academy of Sciences (CAS) has detailed the physical characteristics of chromospheric jets in and around a sunspot, using high-resolution observations from the New ...
