Astronomers believe mysterious signals - previously dismissed as stellar bursts - are coming from an Earth-like planet. 早前被认为是由附近星体出现磁场爆炸造成的光的Gliese 581d近日被天文学家确认存在。 The Gliese 581d planet has conditions that could support life, and is likely to be a rocky world, twice the size of Earth. Gliese 581d行星有着适合人类居住的环境，可能和地球一样存在岩石，体积是地球的两倍。 Signals from the planet were initially discovered in 2010, but last year dismissed as noise from distant stars. 2010年天文学家第一次发现来自Gliese 581d的信号，但是去年这些信号又被科学家认为是其他遥远星球发出的噪音。 Now, a further study claims that the 2017 research was based on 'inadequate analyses of the data' and that Gliese 581d does exist. 而最新研究表明，2017年的数据分析方法不适当，所以Gliese 581d行星可能确实存在。 Last year, Pennsylvania State University researchers said Gliese 581d - and its companion Gliese 581g - were simply a trick of the light caused by magnetic bursts from a local star 22 light-years away. 去年，美国宾夕法尼亚州州立大学的研究人员曾指出Gliese 581d和581g发出的信号不过是距离地球约22光年的一颗星体出现磁场爆发继而造成的光把戏。 |
