[漢羅] 太陽動力學衛星天文台 翕著--ê 太陽日珥爆發

日珥爆發是上壯觀 ê 太陽現象之一。 2011 年，NASA 一台踅太陽行 ê 太陽動力學天文台 太空船 tī 太陽表面 翕著這个 予人印象足深 ê 大型 日珥。 這个戲劇性 ê 爆發是 tī 紫外線波段翕著--ê。 原本 ê 縮時攝影影片 是 90 分鐘久，這支新--ê 是 24 秒 抾一張。 日珥 ê 規模是足大--ê，這个敢若窗仔布 ê 燒氣體，凊凊彩彩 就比 規粒 地球 較大。 日珥 是 受著太陽 磁場 引導、出現 tī 太陽表面 ê 一款短期結構。 無聲 ê 日珥通常會擋一個月左右，而且可能會因為 日冕物質噴射 (CME) 爆發，kā 燒氣體 擲到 太陽系 內底。 產生 太陽日珥 ê 能量 機制，到今一直是一个研究主題。 咱 ê 太陽這馬閣拄著 太陽活動 上強 ê 時期，所以伊這馬是活跳跳，定定會有 日珥爆發 kah CME。 頂禮拜才因為按呢，tī 地球 產生 美麗 ê 極光。

[English] A Solar Prominence Eruption from SDO

One of the most spectacular solar sights is an erupting prominence. In 2011, NASA's Sun-orbiting Solar Dynamic Observatory spacecraft imaged an impressively large prominence erupting from the surface. The dramatic explosion was captured in ultraviolet light in the featured time lapse video covering 90 minutes, where a new frame was taken every 24 seconds. The scale of the prominence is huge -- the entire Earth would easily fit under the flowing curtain of hot gas. A solar prominence is channeled and sometimes held above the Sun's surface by the Sun's magnetic field. A quiescent prominence typically lasts about a month and may erupt in a Coronal Mass Ejection (CME) expelling hot gas into the Solar System. The energy mechanism that creates a solar prominence is a continuing topic of research. Our Sun is again near solar maximum and so very active, featuring numerous erupting prominences and CMEs, one of which resulted in picturesque auroras just over the past week.
