The bubbles display a spectrum with higher peak energies than that of the diffuse gamma-ray glow seen throughout the sky.

气泡结构的光谱呈现出峰值能量高于全天区弥散伽马射线的状态。

But when supermassive black holes at the center of a galaxy feed, the material falling into them heats up, giving off a bright glow across the electromagnetic spectrum.

然而，当星系中心质量超级大的黑洞“吞食”时，落入其中的物质便会升温，发出一道明亮的光，通过电磁波频谱可以显示出来。

Fluorescent colors also reflect or absorb colors in the visible spectrum, but that extra glow in fluorescent colors comes from energy we humans don't see, ultraviolet light.

荧光色也反射或吸收了光谱中的可见光，但是荧光色额外的光来自于人眼看不到的能量，紫外光。

If the light were not infrared but were instead in the visible spectrum, there was enough of it that the naked eye could have seen a glow, according to Phaedon Avouris , manager of nanometer scale science and technology at IBM (nyse: IBM - news - people ) Research Laboratories in Yorktown Heights, N.
