[漢羅] 太陽咧跳舞

有當時仔，咱 ê 太陽表面 敢若是咧跳舞。 比論講，2012 年中，NASA 踅太陽 ê 太陽動力學衛星天文台 就 翕著 一个 予人印象足深 ê 日珥，就敢若咧 跳舞 仝款。 這支 3 點鐘久 ê 縮時攝影影片 是 tī 紫外光波段 翕--ê。 圓箍仔形 ê 磁場 是 太陽 ê 高溫 電漿 流。 這个 咧跳舞 ê 日珥，規模是足大--ê，規粒 地球 攏去予包 tī 這條高溫氣體 弧 內底。 袂出聲 ê 日珥 通常 會擋 一個月，而且有可能會 tī 日冕物質噴射 (CME) 中爆發，kā 高溫氣體 擲到 太陽系 內底。 產生 太陽日珥 ê 能量機制到今猶是一个 研究 主題。 Kah 2012 年仝款，今年太陽表面 ê 活動閣開始變強 矣，嘛開始出現足濟 太陽絲 kah 日珥。

[English] Sun Dance

Sometimes, the surface of our Sun seems to dance. In the middle of 2012, for example, NASA's Sun-orbiting Solar Dynamic Observatory spacecraft imaged an impressive prominence that seemed to perform a running dive roll like an acrobatic dancer. The dramatic explosion was captured in ultraviolet light in the featured time-lapse video covering about three hours. A looping magnetic field directed the flow of hot plasma on the Sun. The scale of the dancing prominence is huge -- the entire Earth would easily fit under the flowing arch of hot gas. 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 still a topic of research. Like in 2012, this year the Sun's surface is again quite active and features many filaments and prominences.
