A red Sunset. The red-hue is explained by the phenomenon of Rayleigh scattering. The sunset is often more brightly coloured than the sunrise because there is more dust at the end of the day than at its beginning. Because the light from the Sun is bent by the variable density of the Earth's atmosphere, the Sun is still seen after it is below the horizon.
