美國東部時間1月20號周日晚午夜將近時,會發生「超級血狼月」的天文奇觀。「超級月亮」、「血月」與「狼月」將同時出現。
Stargazers around the world will have a rare opportunity to witness a three-in-one astronomical spectacle known as the "super blood wolf moon" on Sunday night (EST).
As many as 2.8 billion people across all of North America, parts of Europe, West Africa, and northernmost Russia will have a view of the entire lunar eclipse, which will begin minutes before midnight on the U.S. East Coast (5 a.m. GMT), according to Space.com.
月球沿橢圓形軌道圍繞地球運轉。當滿月出現在近地點時,看起來會比平常大14%,就成為「超級月亮」。
A supermoon happens when a full moon is at the closest point of orbit to earth, which makes it 14 percent larger than its usual appearance.
While spinning, the moon is revolving around earth along an elliptical orbit, one side of which (apogee) is about 30,000 miles (50,000 km) farther from earth than the other (perigee).
月亮本身並不發光,而是反射太陽光。當月全食發生時,地球擋住了太陽光,其大氣層吸收並散射出的紅色光(波長最長)最大程度投射到月球上,使我們看到的月亮呈現鏽紅或血紅色,謂之「血月」。
The so-called blood moon is what we've known as a total lunar eclipse, when the moon turns into a rusty color.
The moon itself doesn't produce light. It shines just because its surface reflects the sun's rays. So when the earth moves into the middle of the sun and the moon, theoretically it will block all the sunlight away from the moon.
據北美天氣期刊《農夫年曆》記載,滿月會引發狼群的嚎叫,所以1月的第一個滿月通常被稱為狼月。科學上並無月亮周期與狼群嚎叫有關的發現,但狼確實在夜間更加活躍,且在嚎叫時會向著月亮(天空)的方向,以便聲音更好地傳遞。
According to the Farmers' Almanac, wolves will make long loud cries during full moon, so the first full moon in January became known as the wolf moon.
你既不需要特殊的天文儀器,也不需要去任何指定地點。
那麼最重要的問題來了:
所以我在哪裡都可以通過肉眼看到這次超級血狼月嗎?
答:
因為發生在中國的白天,你看不到。
CGTN會為你在線直播!
「超級血狼月」大概於北京時間1月21日(明天)中午11點35分開始,至下午2點45分完全結束。
鎖定CGTN的社交媒體平臺,我們將會在月食開始前放出直播入口。
Stay tuned to CGTN's social media for a livestream of this stunning event. No matter where you are, you will be able to witness this interstellar phenomenon through your digital device.
除了明天的「超級血狼月」,以下天文奇觀也值得標註在你的2019日曆上:
