#BlackHoleWeek#

New sonifications of well-known black holes have been released for BlackHoleWeek ! The Perseus galaxy cluster - famous for sound waves detected around its black hole by Chandra, some 57 octaves below middle C.

本周#nasa黑洞周形象# NASA公布了距地球2亿4千万光年的英仙座黑洞发出的声音，该声音被放大了57个八度音 (所谓“音化”，否则人耳听不见)。

该信号由1999年哥伦比亚火箭送入外太空轨道的Chandra X射电望远镜获取。该装置对X射线具有高度敏感性，已经在太空工作了22年。
