NASA发现“超级地球” 或存在生命

GJ 357 d, a super-Earth that is 6.1 times the Earth's mass, is the most intriguing because it orbits the star at a distance where the temperature might be just right to support liquid water on the surface.

另一颗“超级地球”GJ357d的质量是地球的6.1倍，最令研究人员感兴趣，因为它围绕恒星运行的距离使其表面的温度可能刚好适宜液态水的存在。

"GJ 357 d is located within the outer edge of its star's habitable zone, where it receives about the same amount of stellar energy from its star as Mars does from the Sun," said Diana Kossakowski, study co-author at the Max Planck Institute for Astronomy. "If the planet has a dense atmosphere, which will take future studies to determine, it could trap enough heat to warm the planet and allow liquid water on its surface."

“GJ 357 d位于其恒星宜居带的外边缘，它从恒星接收到的能量与火星从太阳接收到的能量差不多，”马克斯普朗克天文研究所的研究合著者戴安娜·科萨科夫斯基说。“如果这颗行星有稠密的大气层，它可能会捕获足够的热量使自身变暖，表面就可以留存液态水，而是否存在大气层还需要进一步研究。”

stellar ['stelə]：adj.恒星的；星球的

一些网友评论说，谁知道那上面是不是已经住满了“人”……

The researchers don't know if the super-Earth is rocky like our own planet, but it orbits the star every 55.7 days and has a temperature of negative 64 degrees Fahrenheit. An atmosphere could cause it to be warmer.
