立體木星近對相
Stereo Jupiter near Opposition

在這兩張屋頂望遠鏡拍攝的影像中,木星看起來非常清晰。這兩張照片都是去年 11 月 17 日從地球上的新加坡拍攝的,當時距離木星 2023 年的衝日點大約兩週。這顆巨大的行星在午夜的天空中高高爬升,距離新加坡只有 33 . 4 光分。這大約是 4 個天文單位的距離。木星的行星腰帶暗帶和光帶以及這個巨大世界的白色橢圓形旋渦都清晰可見。木星標誌性的大紅斑在南面非常突出。木星每 10 個小時在其軸心上快速旋轉一次。因此,根據僅相隔 15 分鐘拍攝的影片幀,這些影像形成了一對立體影像。看著這對影像的中心點,然後轉動你的眼睛,直到獨立的影像匯聚在一起,就能看到三維效果了。當然,木星現在離 2024 年的對沖日已經不遠了。行星地球將於 12 月 7 日從太陽系的主宰氣體巨行星和太陽之間穿過。
原文:Jupiter looks sharp in these two rooftop telescope images. Both were captured last year on November 17 from Singapore, planet Earth, about two weeks after Jupiter's 2023 opposition. Climbing high in midnight skies the giant planet was a mere 33.4 light-minutes from Singapore. That's about 4 astronomical units away. Jupiter's planet girdling dark belts and light zones are visible in remarkable detail, along with the giant world's whitish oval vortices. Its signature Great Red Spot is prominent in the south. Jupiter rotates rapidly on its axis once every 10 hours. So, based on video frames taken only 15 minutes apart, these images form a stereo pair. Look at the center of the pair and cross your eyes until the separate images come together to see the 3D effect. Of course Jupiter is now not far from its 2024 opposition. Planet Earth is set to pass between the Solar System's ruling gas giant and the Sun on December 7.
