超級月亮與月全食中秋同現

  Look up Sunday to see a truly special cosmic event: A supermoon total lunar eclipse.

  Not only will the moon be at its closest point point to Earth in it orbit on Sept. 27, it will also pass completely into Earth's shadow, turning the lunar body into a red-tinted "blood moon" for anyone who has clear, dark skies on the planet's surface.

  "All of South America and most of North and Central America will see the entire eclipse, while those west of roughly 120°W will see it in progress at moonrise," NASA said in a statement. "You won't need special equipment to see it. Just go outside and look up!"

  This will mark the first time a total lunar eclipse during a supermoon has occurred since 1982, and it won't happen again until 2033.

  During a supermoon, the moon can actually look up to 14% larger in diameter; however, everyday skywatchers might not be able to tell the difference.

  Scientists can also collect a fair bit of data about the moon during a lunar eclipse that they wouldn't be able to get otherwise.

  For example, NASA's Lunar Reconnaissance Orbiter (LRO) will be able to take measurements of the moon's surface temperature.

  By learning more about how the temperature of the surface of the moon changes, scientists can actually have new insights about the structure of the surface of the moon, NASA LRO deputy project scientist Noah Petro, said in a NASA video interview.

  周日(9月27日)咱們將見證一個特別的天文征象:超等玉輪和月全食同時湧現。

  9月27日,月球將間隔地球比來,也會完整進入地球的暗影,把玉輪染成一個“血月”。屆時只要有陰郁無遮擋的天空,全球的人都能看到這一奇景。

  “全部南美洲地域,和大部門北美和美洲中部地域將能看到月全食的全部進程,而在西經120°以西地域的人們可以在玉輪上升的時刻視察到。”NASA(美國國度航空航天局)在一次聲明中表現。“你不須要任何特別的裝備,走到表面昂首看就能夠。”

  上一次超等玉輪和月全食同時湧現是在1982年,而下一次將出如今2033年。

  在超等月球湧現的時刻,月球的直徑可以比日常平凡看起來大14%。不外民眾天文視察者其實不必定能視察到這類差別。

  科學家在月蝕時代可以也獲得很多日常平凡沒法獲得的月球數據。

  好比,NASA(美國國度航空航天局)的LRO(美國月球勘察軌道飛翔器)將可以丈量月球外面的溫度。

  “經由過程研討月球外面溫度的變更,科學家們可以對月球外面構造有更新的熟悉”,LRO的助理項目科學家Noah Petro在一次視頻采訪中說。
