WebA Lyman-alpha emitter ( LAE) is a type of distant galaxy that emits Lyman-alpha radiation from neutral hydrogen. Most known LAEs are extremely distant, and because of the finite travel time of light they provide glimpses into the history of the universe. They are thought to be the progenitors of most modern Milky Way type galaxies.

WebTypically, the human eye can detect wavelengths from 380 to 700 nanometers (nm). For comparison, a human hair is about 80,000 nm wide. As the full spectrum of visible light travels through a prism, the wavelengths separate into the colors of the rainbow because each color is a different wavelength, thus refracting, or bending, a different amount.
