英天文學家公佈宇宙空間最詳細地圖
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.
英國天文學家近日公佈了我們臨近宇宙空間迄今最詳細的3D地圖。由英國朴茨茅斯大學主持的2微米紅移巡天(2MRS)項目對距離地球3.8億光年的空間進行觀測記錄，歷時10年完成研究。因受到銀河系塵埃阻擋有一部分區域觀測不到，但此次項目對其進行了詳細記錄，以便更好理解這些區域和其他區域相比對銀河運動的意義。朴茨茅斯大學的凱倫 馬斯特在正在馬薩諸塞州哈佛史密鬆天體物理中心召開的美國天文學會第218次會議上公佈了這一成果。
