Saturn Behind the Moon Explanation: What's that next to the Moon? Saturn. In its monthly trip around the Earth -- and hence Earth's sky -- our Moon passed nearly in front of Sun-orbiting Saturn earlier this week. Actually the Moon passed directly in front ofSaturn from the viewpoints of a wide swath of Earth's Southern Hemisphere. The featured image from Sydney, Australia captured the pair a few minutes before the eclipse. The image was a single shot lasting only 1/500th of a second, later processed to better highlight both the Moon and Saturn. Since Saturn is nearly opposite the Sun, it can be seen nearly the entire night, starting at sunset, toward the south and east. The gibbous Moon was also nearly opposite the Sun, and so also visible nearly the entire night -- it will be full tomorrow night. The Moon will occult Saturn again during every lap it makes around the Earth this year. 月球后方的土星 瞧！月球旁边的天体是什么？答案是土星。 本周早些时候，月球在绕地球一周的旅程中几乎经过了土星的前方。实际上，从地球南半球的广袤地带看去，月球正好在土星前方。 这幅拍摄于悉尼的特征图像呈现了掩食发生前几分钟的景象。这幅照片的曝光时间只有1/500秒，在经过处理后，能更好地突出了月球和土星。因为土星几乎与太阳相对，所以我们可以看到土星在日落时分、从东南方升起，并几乎整晚可见。凸月几乎也与太阳相对，明晚即将呈满月，因此也几乎整晚可见。在今年月球绕地球的运行中，每个月都会出现月掩土星。 图片地址： https://apod./apod/image/1908/MoonSaturn_Patonai_1280.jpg 近期文章： Astronomy Picture of the Day——土星在昼夜平分点 NASA微店 欢迎大家选购 |
