NASA于本月初以“M81 Galaxy is Pretty in Pink”发布了最新的得到的M81空间望远镜图片。补充一下,蓝色表示紫外波段,黄白色表示可见光,红色代表红外波段(The colors in this picture represent a trio of light wavelengths: blue is ultraviolet light captured by the Galaxy Evolution Explorer; yellowish white is visible light seen by Hubble; and red is infrared light detected by Spitzer. )
