In the 1860s, Tyndall did a number of experiments with light, shining beams through various gases and liquids and recording the results. In doing so, Tyndall discovered that when gradually filling the tube with smoke and then shining a beam of light through it, the beam appeared to be blue from the sides of the tube but red from the far end.

It is based on the reddish glow of the morning or evening sky, caused by trapped particles scattering the blue light from the sun in a stable air mass. [ 5 ] If the morning skies are of an orange-red glow, it signifies a high-pressure air mass with stable air trapping particles, like dust, which scatters the sun's blue light.
It is also called sky radiation, the determinative process for changing the colors of the sky. Approximately 23% of direct incident radiation of total sunlight is removed from the direct solar beam by scattering into the atmosphere; of this amount (of incident radiation) about two-thirds ultimately reaches the earth as photon diffused skylight ...

Wood told Travel + Leisure he snapped the photos around 12:50 a.m."I just wish I had been more prepared; it came out of nowhere when we were out getting food," he said. People were quick to jump ...
The skies over St. Petersburg, Florida, turned purple as Hurricane Milton approached the Florida coast last week, a phenomenon that has been seen in other hurricanes such as Delta, Dorian, and ...
Rayleigh scattering causes the blue color of the daytime sky and the reddening of the Sun at sunset. Rayleigh scattering (/ ˈ r eɪ l i / RAY-lee) is the scattering or deflection of light, or other electromagnetic radiation, by particles with a size much smaller than the wavelength of the radiation.
Blue hour at the Old Cathedral of the Holy Name of Jesus, Bragança in Portugal. The blue hour (from French l'heure bleue; [1] [a] pronounced [lœʁ blø]) is the period of twilight (in the morning or evening, around the nautical stage) when the Sun is at a significant depth below the horizon.
