[漢羅] 三重凌木現象 kah 互食事件

這三張相片是 8 月 15 tī 菲律賓 Cebu 市翕 ê 太陽系 氣態巨行星,木星。 Tī 這工,拄仔好望遠鏡看著 一寡精彩景色 ê 詳細狀況,是木星加利略衛星 ê 凌木現象。 上面頂彼張,是 Io tī 上正爿去予木星 ê 烏影閘去。 毋閣其他三粒大粒 ê 木衛出現 tī 木星 一條一條雲帶盤面 ê 頭前。 較光 ê Europa kah 較暗 ê Ganymede tī 較倚倒爿遐。 In ê 烏影 to̍h 照 tī 氣態巨行星 ê 雲頂。 Callisto tī 木星正爿下跤 ê 邊仔。 三粒衛星 tī 木星表面產生這个三重凌木現象。 中央彼張,Europa kah Ganymede ê 烏影 tī 中央看會著。 毋閣 Ganymede ùi Europa 頭前行過,kā 伊閘牢矣。 下跤彼張,是凌木現象真罕得看著 ê 木衛食。 Ganymede ê 烏影 to̍h 落 tī Europa 面頂。 Ùi 地球 ê 角度來看,加利略衛星會閘來閘去、食來食去。 這款現象 6 年出現一改,差不多是 木星 tī 伊春分附近 ê 時陣 會當看著。

[English] Triple Transit and Mutual Events

These three panels feature the Solar System’s ruling gas giant Jupiter on August 15 as seen from Cebu City, Phillipines, planet Earth. On that date the well-timed telescopic views detail some remarkable performances, transits and mutual events, by Jupiter’s Galilean moons. In the top panel, Io is just disappearing into Jupiter’s shadow at the far right, but the three other large Jovian moons appear against the planet’s banded disk. Brighter Europa and darker Ganymede are at the far left, also casting their two shadows on the gas giant’s cloud tops. Callisto is below and right near the planet’s edge, the three moons in a triple transit across the face of Jupiter. Moving to the middle panel, shadows of Europa and Ganymede are still visible near center but Ganymede has occulted or passed in front of Europa. The bottom panel captures a rare view of Jovian moons in eclipse while transiting Jupiter, Ganymede’s shadow falling on Europa itself. From planet Earth’s perspective, similar mutual events, when Galilean moons occult and eclipse each other, can be seen every six years or so when Jupiter is near its own equinox.
