”钻石行星“英语怎么说
名词解释:钻石行星看上去表面散布钻石,实际上为岩石行星。钻石行星的表面上不存在水源,主要组成成分是碳(石墨和钻石)、铁、碳化硅以及未定的硅酸盐。你知道怎么用英语表达吗?
Scientists on Thursday reported the existence of a "diamond planet" twice the size of Earth, and eight times its mass, zooming around a nearby star.
In fact, this is not the first diamond planet ever discovered, but it is the first found orbiting a sun-like star.
The discovery means that distant rocky planets can no longer be assumed to have chemical constituents, interiors, atmospheres, or biological conditions similar to those of Earth, said lead researcher Nikku Madhusudhan, a Yale postdoctoral researcher in physics and astronomy.
科学家周四宣布,他们发现一颗“钻石行星”围绕着周围一颗恒星运动,它的大小是地球的两倍,质量为地球的8倍。事实上,这不是第一次被发现的钻石行星,但却是首次被发现的绕类太阳恒星运动的钻石行星。耶鲁大学物理与天文博士后研究员、首席研究员Nikku Madhusudhan称,这一发现意味着遥远的岩石行星不再需要假设与地球拥有类似的化学组成、内部、大气或生物条件。
