北京時(shí)間1月31日晚,天文愛(ài)好者等待已久的“超級(jí)藍(lán)月”+“月全食”將在天幕現(xiàn)身。該準(zhǔn)備哪些長(zhǎng)槍短炮?用手機(jī)如何拍出最美照片?觀月還需儲(chǔ)備哪些知識(shí)點(diǎn)?收下這份觀月攻略,讓你有備而去,盡興而歸。

此次“超級(jí)藍(lán)月”與月全食組合為何如此受矚目?
其實(shí),“藍(lán)月”并不稀有,但如果“藍(lán)月”是一顆“超級(jí)月亮”,又同時(shí)發(fā)生月全食,那就是十分罕見(jiàn)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,你會(huì)同時(shí)看到肉眼可見(jiàn)的超級(jí)月亮和月全食。超級(jí)月亮指的是在繞地運(yùn)行軌道上處于近地點(diǎn)的滿月。作為1月第二次滿月,這次超級(jí)月亮也被稱為超級(jí)藍(lán)月。這種天文上的巧合是150多年來(lái)首次出現(xiàn),也就是說(shuō)有人一輩子都沒(méi)有見(jiàn)過(guò),而未來(lái)十年都不會(huì)重現(xiàn)。
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.
這次超級(jí)月亮還是一連三次超級(jí)月亮的最后一次——前兩次發(fā)生在2017年12月3日和2018年1月1日。
