The most complete 3D map of the local universe has been unveiled by British astronomers. The 2MASS Redshift Survey (2MRS) from the University of Portsmouth extends to a distance of 380 million light years and has taken 10 years to complete. The survey has mapped in detail areas previously hidden behind the Milky Way to better understand the impact they have on its motion in relation to the rest of the universe. Karen Masters from the University of Portsmouth presented the map in a press conference at the 218th meeting of the American Astronomical Society in the Harvard-Smithsonian Centre for Astrophysics (CfA) in Cambridge, Massachusetts.
英国天文学家近日公布了我们临近宇宙空间迄今最详细的3D地图。由英国朴茨茅斯大学主持的2微米红移巡天(2MRS)项目对距离地球3.8亿光年的空间进行观测记录，历时10年完成研究。因受到银河系尘埃阻挡有一部分区域观测不到，但此次项目对其进行了详细记录，以便更好理解这些区域和其他区域相比对银河运动的意义。朴茨茅斯大学的凯伦 马斯特在正在马萨诸塞州哈佛史密松天体物理中心召开的美国天文学会第218次会议上公布了这一成果。
