[漢羅] Webb 太空望遠鏡 tī 紅外線波段翕 ê 木星 kah 木星環

是按怎木星有環？ 木星主要 ê 環 是 1979 年 NASA 航海家 1 號 太空船飛過木星 ê 時陣翕著--ê。 毋閣環是按怎來--ê，彼陣咱猶毋知。 等到 NASA 加利略 太空船 tī 1995 年到 2003 年 踅木星咧行 ê 時陣，有證實一个假說。 講，木星環 是 流星體 挵著木星附近 ê 細粒衛星，才產生--ê。 比論講，若是有一粒細粒流星體 挵著木星足細粒 ê 衛星 Metis。 這粒流星體會鑽入去衛星內底、蒸發、爆炸，kā 產生 ê 塗粉擲入去 踅木星 ê 軌道。 這張 木星相片是 James Webb 太空望遠鏡 tī 紅外線波段 翕--ê。 這毋若看會著 木星 kah 木星雲，嘛看會著木星環。 咱嘛看會著木星 ê 大紅斑 (GRS)，就是正爿較淺色彼丸。 木星上大粒 ê 衛星 木衛二 Europa 就 tī 倒爿彼个 繞射光尖 ê 中心。 木衛二 Europa ê 烏影，就 tī 大紅斑 ê 邊仔。 這張相片內底有幾若个特徵，咱到今 猶毋是蓋清楚。 比論講木星正爿邊界，敢若有一重 kah 木星 分開 ê 雲層。

[English] Jupiter and Ring in Infrared from Webb

Why does Jupiter have rings? Jupiter's main ring was discovered in 1979 by NASA's passing Voyager 1 spacecraft, but its origin was then a mystery. Data from NASA's Galileo spacecraft that orbited Jupiter from 1995 to 2003, however, confirmed the hypothesis that this ring was created by meteoroid impacts on small nearby moons. As a small meteoroid strikes tiny Metis, for example, it will bore into the moon, vaporize, and explode dirt and dust off into a Jovian orbit. The featured image of Jupiter in infrared light by the James Webb Space Telescope shows not only Jupiter and its clouds, but this ring as well. Also visible is Jupiter's Great Red Spot (GRS) -- in comparatively light color on the right, Jupiter's large moon Europa -- in the center of diffraction spikes on the left, and Europa's shadow -- next to the GRS. Several features in the image are not yet well understood, including the seemingly separated cloud layer on Jupiter's right limb.
