21厘米和莱曼阿尔法线是氢光谱两端的主要发射线。每条线可以用于创建大尺度结构的三维强度图。由于莱曼α辐射，在低红移时天空亮度估计为0.4焦耳/球面度，比黄道光前景亮。
The 21-cm and Lyman Alpha lines are the dominant line-emission spectral features at opposite ends of the spectrum of hydrogen. Each line can be used to create three dimensional intensity maps of large scale structure. The sky brightness at low redshift due to Lyman Alpha emission is estimated to be 0.4 Jy/Steradian, which is brighter than the zodiacal light foreground.
