[漢羅] 太陽軌道太空船 翕著 創記錄 ê 太陽日珥

咱 ê 太陽 sī 發生啥物代誌？ 頂個月，咱才拄翕著 有史以來 上大 ê 太陽 日珥 kah 規个太陽盤。 這張 創記錄 ê 影像，sī 踅太陽 ê 太陽 軌道 太空船 tī 紫外光波段 翕 ê。 恬去 ê 太陽日珥 sī 太陽表面 ê 高溫氣體雲，sī 太陽磁場 leh 控制 ê。 這个 太陽日珥 實在 sī 有夠大 ê，伊 ê 闊度 kah 太陽直徑 有通比。 太陽日珥 ê 爆發 實在 sī 真歹臆，伊會利用 日冕物質噴出事件 (CME) kā 噴出來 ê 高溫氣體 擲到 太陽系 內底。 CME 若是挵著地球 kah 伊 ê 磁層，可能 to̍h 會 產生足光 ê 極光。 雖罔講太陽日珥 確實會產生 CME 現象，毋閣伊這擺 ê 方向毋是 tùi 地球來。 咱這馬已經知影 日珥 kah 太陽磁場 ê 改變有關係，毋閣 產生 太陽日珥 ê 能量機制 到今猶是一个 研究主題。

[English] Record Prominence Imaged by Solar Orbiter

What's happened to our Sun? Last month, it produced the largest prominence ever imaged together with a complete solar disk. The record image, featured, was captured in ultraviolet light by the Sun-orbiting Solar Orbiter spacecraft. A quiescent solar prominence is a cloud of hot gas held above the Sun's surface by the Sun's magnetic field. This solar prominence was huge -- spanning a length rivaling the diameter of the Sun itself. Solar prominences may erupt unpredictably and expel hot gas into the Solar System via a Coronal Mass Ejection (CME). When a CME strikes the Earth and its magnetosphere, bright auroras may occur. This prominence did produce a CME, but it was directed well away from the Earth. Although surely related to the Sun's changing magnetic field, the energy mechanism that creates and sustains a solar prominence remains a topic of research.
