Document Summary
3the distance between consecutive crests of a wave. This serves as a unit of measure of electromagnetic radiation. A very small, white star formed when an average sized star uses up its fuel supply and collapses. This process often produces a planetary nebula, with the white dwarf star at its center. Electromagnetic radiation of a very short wavelength and very high-energy. X-rays have shorter wavelengths than ultraviolet light but longer wavelengths than cosmic rays. The field of astronomy that studies celestial objects by the x-rays they emit. A bright celestial object that gives off x-rays as a major portion of its radiation. An ordinary star such as the sun at a stable point in its evolution. An imaginary belt across the sky in which the sun, moon, and all of the planets can always be found. A faint cone of light that can sometimes be seen above the horizon after sunset or before sunrise.
