"三體"真實存在：科學家發現擁有三顆太陽的行星
Scientists discover bizarre world with three suns, 300-year seasons
"Star Wars" fans love Tatooine and its twin suns, but astronomers working with one of the world's biggest telescopes have done Luke Skywalker's home planet one better.
《星球大戰》中的塔圖因星球（Tatooine,天行者家族的故鄉行星）以及它所繞行的雙子太陽深受粉絲的喜愛,然而日前天文學家們利用世界上最大的天文望遠鏡之一發現了一個比盧克·天行者的故鄉所在的星球更勝一籌的行星.
They've discovered a bizarre world with not two but three suns ― and seasons that last longer than a human lifetime.
他們發現了一個奇妙的新世界,在這里,你能看到不止兩個太陽,而是三個,同時,每一個季節都比人類的一生還要漫長.
Known as HD 131399Ab, the unusual exoplanet is located 320 light-years from Earth in the large southern constellation Centaurus. It's a gas giant like Jupiter but about four times as massive.
這顆不同尋常的地外行星被命名為HD 131399Ab, 它位于南方巨大的人馬星座上,距地球320光年.它是類似于木星的氣體巨星,但它的體積是木星的四倍.
And while it's one of the coldest exoplanets ever to be directly imaged by a telescope (rather than detected as a result of the dimming of starlight as it passes in front of its host star), HD 131399Ab is very hot by human standards. The average temperature exceeds 1,000 degrees Fahrenheit.
雖然它是溫度最冷的地外行星中被天文望遠鏡直接捕捉到影像的一個（而不是在從其宿星前經過時被檢測到一抹暗淡的星光）,HD 131399Ab星球上的平均溫度超過華氏1000度,遠超人類耐熱標準.
In short, HD 131399Ab isn't the kind of place you'd like to call home. (And there's no hint that it harbors alien life.) But if you could live there, you'd find its sky a most peculiar place: You'd see either constant daylight or triple sunsets, depending on the season.
簡而言之,HD 131399Ab行星絕不是一個宜居的地方（并且這里也沒有發現外星生命跡象）.但是如果你有機會住在那兒,你會看到最光怪陸離的天空：根據季節的不同,你可能看到永晝,也有可能同時欣賞三個落日.
And each season on HD 131399Ab lasts about 300 years.
HD 131399Ab行星的每一個季節都持續三百年左右.
