位於夏威夷茂宜島的美國國家科學基金會「丹尼爾·井上太陽望遠鏡」（DKIST），在太陽物理學領域達成了新的里程碑。
By capturing the first detailed maps of the Sun’s coronal magnetic field, scientists can now observe the outer atmosphere where solar storms and flares originate.
過去，繪圖僅限於太陽表面，但這台全球最強大的太陽望遠鏡改變了這一點。
Previously, mapping was limited to the Sun's surface, but the world’s most powerful solar telescope has changed this.
該望遠鏡利用稱為日冕儀技術的先進方法創造出人工日蝕，能偵測到比太陽盤面微弱十億倍的磁訊號。
Using an advanced technique called coronagraphy to create an artificial eclipse, the telescope detects magnetic signals a billion times fainter than the solar disk.
透過分析塞曼效應下的光譜線分裂，研究人員能以極高精度測量磁場強度。
By analyzing spectral line splitting through the Zeeman Effect, researchers measure magnetic strength with incredible precision.
近期的影像甚至揭示了細小的開爾文-亥姆霍茲不穩定性，這對於理解磁能如何作為爆炸性事件釋放至關重要。
Recent images have even revealed tiny, swirling Kelvin-Helmholtz instabilities, which are crucial for understanding how magnetic energy is released as explosive events.
這些發現對於太空天氣預報至關重要。
Just as we monitor Earth’s weather, mapping these invisible solar forces helps us protect critical infrastructure, including satellites, power grids, and GPS systems, from potential technological disruptions.
憑藉其4公尺口徑與高解析度成像，DKIST正為驅動我們太陽系的複雜且強大的力量投射出新的光芒。
With its 4-meter aperture and high-resolution imaging, DKIST is shedding new light on the complex, powerful forces driving our solar system.
