月亮临边旁的火星

Explanation: Does the Moon ever block out Mars? Yes, the Moon occasionally moves in front of all of the Solar System’s planets. Just this past Sunday, as visible from some locations in South America, a waning gibbous Moon eclipsed Mars. The featured image from Córdoba, Argentina captured this occultation well, showing a familiar cratered Moon in the foreground with the bright planet Mars unusually adjacent. Within a few seconds, Mars then disappeared behind the Moon, only to reappear a few minutes later across the Moon. Today the Moon moves close to, but not in front of, Venus. Because alignments will not have changed by much, the next two times the Moon passes through this part of the sky – in early September and early October – it will also occult Mars, as seen from parts of South America.

说明: 会发生月掩火星吗？会的。月亮偶而会通过太阳系任何一颗行星的前方；例证之一就出现在上个星期日，当时从南美洲的一些地点看出去，亏凸月掩过火星。这幅摄于阿根廷科尔多瓦市的主题影像，佳妙的捕捉到坑坑疤疤月盘紧贴着明亮的火星。接着在短短的数秒钟，火星就隐没在月亮后方，然后在数分钟之后，火星越过月盘复现于另一侧。在今天，月亮会通过金星附近，但并未发生掩食金星。在今年九月初和十月初，当月亮接连二次再通过相同的天区时，因为这些天体的相对排列变化不大，届时从南美洲的某些地点看出去，会再发生月掩火星。
