Clouds of hydrogen in space often emit light with a wavelength of 656.3 nanometers. This type of light is emitted from galaxies that are moving away from Earth at great speed. When astronomers detect photons of this type from those galaxies, those photons of light will, have a longer wavelength and more energy than the emitted light or have a longer wavelength and less energy than the emitted light
