Alaska Highway Rainbow

Like a portal to wild spaces, a double rainbow hangs over the Alaska Highway in British Columbia, Canada. While rainbows display a brilliant array of colors, most of the radiation in the universe, from very long wavelengths picked up by radios to ultrashort ones seen by special x-ray and gamma-ray detectors, lies outside the rainbow of visible light.
