[漢羅] 木星表面的木衛烏影

木星表面彼个大烏點是啥物？ 彼是 木衛三 Ganymede 的烏影。 伊是 木星 上大粒的衛星。 木衛 若是行到木星四大衛星佮太陽之間，in 就會佇木星表面 產生烏影。 這就和 月娘行到 地球佮太陽之間仝款。 佮佇地球仝款，你若是 chhāi 佇 木星表面的烏影 遐，木衛就會共太陽完全閘去，按呢你就會看著 日全食 矣。 毋閣佮地球無仝的是，木衛的烏影 會定定出現。 閣較無四常 的是，太空船離 in 有夠近的，才會記錄著這張 高解析度 的 影像。 Juno 太空船 佇二月底彼陣飛到 木星 附近，所以離太空船較近的木星雲佮木衛的烏影才會看起來 遮爾大。 木星是 太陽系 上大粒的行星。 Juno 太空船已經佇木星面頂，揣著足濟新的發現，嘛包括最近 高速擴大的圓形極光。

[English] Moon Shadow on Jupiter

What is that large dark spot on Jupiter? It’s the shadow of Ganymede, one of Jupiter’s largest moons. When Jupiter’s moons cross between the Jovian giant and the Sun, they created shadows just like when the Earth’s moon crosses between the Earth and the Sun. Also like on Earth, if you were in a dark shadow on Jupiter, you would see a moon completely eclipse the Sun. Unlike on Earth, moon shadows occur most days on Jupiter – what’s more unusual is that a spacecraft was close enough to record one with a high-resolution image. That spacecraft, Juno, was passing so close to Jupiter in late February that nearby clouds and the dark eclipse shadow appear relatively large. Juno has made many discoveries about our Solar System’s largest planet, including, recently, rapidly expanding circular auroras.
