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] - The telescope recorded numerous dark coronal loops during the decay phase of 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 dark filamentous loops observed may represent the basic components of solar flares, enabling a clearer understanding of magnetic arc bundles and individual loops [2] - The images captured by the telescope depict stunning structures, with dark loops arching and a clearly defined triangular bright area at the center, showcasing the complexity and grandeur of solar phenomena [2] - Researchers assert that humanity has finally reached the essence of the solar coronal loop structure, enhancing the understanding of solar dynamics [2]
