The researchers tested their new black material with near-infrared radiation, just beyond the red end of the visible spectrum.

Because these different forms of electromagnetic radiation - on this "simplistic" level - are fundamentally so similar, they are today commonly viewed as composing a single spectrum.

因为这些各异的电磁辐射在“简单”层面上，即本质上是如此相似，所以如今把它们视为一个光谱中的组成部分。

Because radiation from the Crab nebula is so energetic, the electrons that created it must have been travelling very close to the speed of light so close that the difference between the two speeds would bump up against Planck-scale graininess, and show up in the spectrum of the radiation.

"Oxybenzone is one of the few FDA-approved ingredients that provides effective broad spectrum protection from UV radiation, and has been approved for use since 1978, " said Dr. Daniel M.

The new work focuses instead on cold, dense masses of gas that have markedly less random motion, and which emit their radiation in the microwave part of the electromagnetic spectrum.
