Web22. feb 2024 · As the stars grow older they cool down, which means that the light they emit has more red light (compare to a fire burning bright yellow when it's hot and a darker red when cooling down). This shift affects the overall distribution of the emitted light, but importantly does not affect the absorption lines, which stay in the same place (color). Web7. máj 2024 · The concept is key to charting the universe's expansion. Visible light is a spectrum of colors, which is clear to anyone who has looked at a rainbow. When an object moves away from us, the light is shifted to the red end of the spectrum, as its wavelengths get longer. If an object moves closer, the light moves to the blue end of the spectrum ...
