An exoplanet, called WASP-12b which is about 1,200 light years from Earth and 1.4 times the mass of Jupiter has been considered suitable for life existence, although a little hot. And its sibling planets could even be made of diamonds, according to new research findings.

　　最新研究结果显示，一颗名为WASP-12b、距离地球1200光年、质量为木星1.4倍的系外行星适合生命存在，尽管热了一点。而与其同属一个星系的情况更甚：它们有可能由钻石构成。

A team led by researcher Nikku Madhusudhan of Princeton University and scientist Joe Harrington of the University of Central Florida monitor WASP-12b during one of its orbits, particularly in the instants before it passed behind its home star. In those brief moments, the light from the star would flow through the planet's atmosphere, allowing astronomers to study the wavelengths produced and infer the atmosphere's chemical composition.

　　由美国普林斯顿大学的研究员尼库 马杜苏丹和佛罗里达中部大学的科学家乔 哈林顿领导的一个研究小组检测WASP-12b的一次绕轨运行情况，特别是在它从其母恒星后面经过的那一刻。在这一刹那，恒星发出的光会穿透行星的大气，天文学家得以研究产生的波长，并推断行星大气的化学成分。

　They found some exoplanets, WASP-12b included, have carbon-rich chemistry: Some have atmospheres with a carbon-to-oxygen ratio of about 0.5. As for WASP-12b, however, there was more than twice the concentration of carbon as usual and almost 100 times more methane than expected.
