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.

With knowledge, however, otherwise worthless matter and radiation turns into petroleum, microchips, and radio spectrum.

When we talk about telescopes, we're usually referring to devices that "see" the visual spectrum of light, but astronomers also build telescopes that gather radiation like radio waves and X rays in order to peer deep into outer space.
