井上望远镜拍到最清晰太阳耀斑图像，揭示日冕回路微观结构

Core Insights - The Daniel K. Inouye Solar Telescope has captured the clearest images of solar flares to date at H-α wavelength (656.28 nm), marking a significant advancement in solar observation [1][2] - The telescope recorded numerous dark coronal loops during an X1.3-class flare, with an average width of 48.2 kilometers and a minimum width of 21 kilometers, setting a record for the narrowest coronal loops observed [1] - This breakthrough allows scientists to directly study the fundamental processes driving flares, such as magnetic reconnection, which were previously only theorized [1] Group 1 - The Inouye Telescope's observations provide a direct view of coronal loops, which are plasma arcs along solar magnetic field lines, often appearing before flares [1] - The ability to observe these structures at such a fine scale enables researchers to investigate the core mechanisms behind flare occurrences [1][2] - The imagery produced by the telescope is described as stunning, with dark filamentous loops resembling a glowing archway, allowing even non-experts to appreciate the complexity and beauty of solar phenomena [2] Group 2 - The previous theoretical predictions suggested that the width of these loops could range from 10 kilometers to 100 kilometers, but direct observation was hindered by resolution limitations [1] - The Inouye Telescope's capability to capture these details represents a leap forward in solar physics, providing insights that were previously confined to theoretical models [1] - The findings may have implications for understanding solar storms and their potential impact on Earth's critical infrastructure [1]
