Astronomers have announced the possible discovery of the first known moon outside our Solar System.天文学家此前宣布,她们有可能在我们的太阳系外找到第一颗不明的月球表面。This exomoon is not like any in our cosmic neighbourhood: its the size of Neptune and orbits a planet the size of Jupiter -- but with 10 times the mass.这颗“系外月球表面”与大家宇宙空间里的任何东西都各有不同:它的身型有海王星那么大,绕着一颗木星尺寸的行星旋转--但这颗行星的品质是木星的10倍。The object was spotted in data from Nasas Kepler spacecraft, and later observed using the Hubble telescope.在该星体划归美国nasa开普勒探测仪的数据信息后,天文学家用以哈勃望远镜进行了观测。

Astronomers David Kipping and Alex Teachey have published their results in Science Advances journal.天文学家杰弗里·恩祥合阿莱克斯·提彻一并她们的成效公布发布在《科学进展》杂志期刊上。But they say that further observations are needed to understand the distant planetary system.可是她们答复,务必更进一步的认真观察才可以讲解这一太远的行星系。Weve tried our best to rule out other possibilities such as spacecraft anomalies, other planets in the system or stellar activity, but were unable to find any other single hypothesis which can explain all of the data we have, said Dr Kipping, from Columbia University in New York.来源于纽约市宾夕法尼亚大学的基平博士称作:“对所观测到的状况,大家已不遗余力逃避别的概率,如探测仪发现异常、太阳系行星中的别的行星或行星主题活动,但我们无法找寻一切别的单一假定来表明大家的数据信息。”To date, astronomers have discovered more than 3,500 exoplanets -- worlds orbiting stars other than the Sun.目前为止,天文学家已寻找高达3500颗系外行星--即环绕着除太阳光之外经营的星体。

A hunt for exomoons -- bodies that orbit these distant planets -- has proceeded in parallel. But so far, these natural satellites have lingered at the limits of detection with current techniques.天文学家也在另外寻找“系外月球表面”--即围绕很远行星的星体。但到迄今为止,这种纯天然星体难以被目前技术性的观测到。The researchers monitored a planet known as Kepler 1625b as it passed in front of its parent star.科学研究工作人员是在这里颗被取名为开普勒1625b的星体环绕着其母星经营的情况下,对其进行的检测。
