A thick atmosphere has been detected around a planet that’s twice as big as Earth in a nearby solar system, researchers reported Wednesday.
研究人員週三報告，在附近的太陽系中發現1顆比地球大2倍的行星，周圍有厚厚的大氣層。
The so-called super Earth — known as 55 Cancri e — is among the few rocky planets outside our solar system with a significant atmosphere, wrapped in a blanket of carbon dioxide and carbon monoxide. The exact amounts are unclear.
所謂的超級地球—被稱為55 Cancri e—是我們太陽系外少數幾個具有重要大氣層的岩石行星之一，被二氧化碳和一氧化碳的層包裹。確切的數量尚不清楚。
“It’s probably the firmest evidence yet that this planet has an atmosphere,” said Ian Crossfield, an astronomer at the University of Kansas who studies exoplanets and was not involved with the research.
「這可能是迄今為止最確鑿的證據，表明這顆行星有大氣層，」研究系外行星的堪薩斯大學天文學家伊恩‧克羅斯菲爾德說，他沒有參與該研究。
Super Earth refers to a planet’s size — bigger than Earth but smaller than Neptune. The boiling temperatures on this planet — which can reach as hot as 4,200 degrees Fahrenheit (2,300 degrees Celsius) – mean that it is unlikely to host life.
超級地球指的是行星的大小—比地球大，但比海王星小。這顆行星上的沸騰溫度可達華氏4200度（攝氏2300度），意味著它不太可能存在生命。
