On March 6, 2025, at 10:00 PM in Torrance, California (at El Camino College), Jupiter was prominently visible in the night sky, accompanied by its four largest moons—Io, Europa, Ganymede, and Callisto—collectively known as the Galilean moons.
2025 年 3 月 6 日晚上 10：00，在加利福尼亞州托倫斯（埃爾卡米諾學院），木星在夜空中顯眼可見，伴隨著它的四顆最大的衛星——木衛一、木衛二、木衛三和木衛四——統稱為伽利略衛星。
Jupiter and Its Moons on March 6, 2025
木星及其衛星 2025 年 3 月 6 日
At that time, the Moon was in a waxing gibbous phase, approximately 54% illuminated, and positioned about 9.8° to the upper left of Jupiter. This close proximity made for a striking celestial pairing in the southwestern sky. When the Curves Line Up
當時，月亮處於盈凸月相，大約 54% 被照亮，位於木星左上角約 9.8° 處。如此接近在西南天空中形成了引人注目的天體配對。 當曲線對齊時
The Galilean moons were arranged in a configuration that, depending on your telescope’s orientation, might have appeared as follows:
伽利略衛星的排列方式可能如下所示，具體取決於您的望遠鏡的方向：
- Io: Closest to Jupiter, possibly to the left.
木衛一 ：最靠近木星，可能在左邊。 - Europa: Near Io, slightly farther out.
木衛二 ：靠近木衛一，稍遠一些。 - Ganymede: Farther from Jupiter, perhaps to the right.
木衛三 ： 離木星更遠，也許在右邊。 - Callisto: The most distant, possibly on the same side as Ganymede.Sky & Telescope+1Space+1
木衛四 ： 最遠的，可能與木衛三在同一側。 天空與望遠鏡+1 空間+1
This arrangement would have been visible through small telescopes or even good binoculars, offering a clear view of Jupiter’s moons lined up along its equatorial plane.
這種排列可以通過小型望遠鏡甚至好的雙筒望遠鏡看到，可以清楚地看到沿著赤道平面排列的木星衛星。
Observing Tips 觀察提示
- Telescope Orientation: Note that telescope optics can invert or mirror images. A Newtonian reflector, for instance, produces an inverted view, while a refractor with a diagonal may mirror the image.
望遠鏡方向 ：請注意，望遠鏡光學元件可以反轉或鏡像圖像。例如，牛頓反射鏡會產生倒置的視圖，而具有對角線的折射鏡可能會鏡像圖像。 - Moon Visibility: The bright Moon nearby could cause some glare, so using a moon filter or observing when the Moon is lower in the sky might enhance visibility of Jupiter’s moons.
月亮能見度 ：附近的明月可能會引起一些眩光，因此使用月亮濾光片或觀察月亮何時在天空中較低可能會提高木星衛星的能見度。 - Timing: Observing earlier in the evening, when Jupiter is higher in the sky, can provide a clearer view with less atmospheric distortion.
計時 ：在傍晚早些時候進行觀測，此時木星在天空中的位置較高，可以提供更清晰的視野，減少大氣失真。
