2025年1月13日，满月与满火星在地球夜空中相遇，呈现出明亮且相对的景象。在北美和非洲部分地区，火星甚至被月球遮挡，形成罕见的月掩火星现象。这张来自美国弗吉尼亚州里士满的合成图像序列记录了这一天文事件，通过每两分钟一次的曝光，捕捉了月球掩星前后火星的轨迹。由于月球的视运动速度略有不同，火星的轨迹呈现出轻微的弯曲。下次火星被月球遮挡将发生在2月9日，虽然仅在地球部分地区可见，但月亮与火星的近距离相遇将更广泛地被观察到。

🌕 2025年1月13日，地球夜空上演满月与满火星同辉的景象，两者在天空中明亮且相对。

🔭 在北美和非洲部分地区观测到罕见的月掩火星现象，火星短暂地被月球遮挡。

📸 通过连续拍摄的图像序列，可以观察到火星在月球掩星过程中呈现出的轻微弯曲轨迹，这是由于月球视运动速度的差异造成的。

📅 下一次月掩火星事件将发生在2月9日，但仅在部分地区可见，而月亮与火星的近距离相遇将更广泛地被观测到。

Astronomy Picture of the Day Discover the cosmos!Each day a different image or photograph of our fascinating universe isfeatured, along with a brief explanation written by a professional astronomer.2025 January 18 Full Moon, Full Mars Image Credit &Copyright:David Bowman Explanation: On January 13a Full Moon and a Full Mars were close,both bright and opposite the Sun in planet Earth's sky.In factMars was occulted, passing behind the Moon, whenviewed from some locations in North America and northwest Africa. As seen from Richmond, Virginia, USA, this compositeimage sequence follows the eveninglunar occultation before, during, and after the much anticipatedcelestial spectacle.The telescopic time series is constructed from an exposure made every twominutes while tracking the Moon over the hours encompassing the event.As a result, the Red Planet's trajectory seems to followa gently curved path due to theMoon's slightly different rate of apparent motion.The next lunar occultation of bright planet Mars will beon February 9 when the moon is in a waxing gibbous phase.Lunar occultations are only ever visible from a fraction of theEarth's surface, though.TheFebruary 9 occultation of Mars will be seen from parts ofRussia, China, eastern Canada, Greenland and other(mostly northern) locations,but a close conjunction of a bright Moon with Mars will be morewidely visible from planet Earth.
