此次“超级蓝月”与月全食组合为何如此受瞩目?
其实,“蓝月”并不稀有,但如果“蓝月”是一颗“超级月亮”,又同时发生月全食,那就是十分罕见的天象。
On January 31, you will be treated to both a visible supermoon—what we call a full moon at its closest orbital point to Earth—and a total lunar eclipse. As the second full moon of the month, it earns the title of a blue moon as well. The celestial coincidence hasn’t happened in more than 150 years. That means there were people who lived and died on this Earth without ever having had a chance to see this phenomenon, which won’t reappear again for another decade.
1月31日,你会同时看到肉眼可见的超级月亮和月全食。超级月亮指的是在绕地运行轨道上处于近地点的满月。作为1月第二次满月,这次超级月亮也被称为超级蓝月。这种天文上的巧合是150多年来首次出现,也就是说有人一辈子都没有见过,而未来十年都不会重现。
This supermoon also happens to be the final one in a supermoon trilogy—the first two of which appeared on Dec. 3 and Jan. 1.
这次超级月亮还是一连三次超级月亮的最后一次——前两次发生在2017年12月3日和2018年1月1日。
