The sky can turn a multitude of colors such as red, orange, pink and yellow (especially near sunset or sunrise) and black at night. Scattering effects also partially polarize light from the sky, most pronounced at an angle 90° from the Sun.
Particles in the air scatter short-wavelength light (blue and green) through Rayleigh scattering much more strongly than longer-wavelength yellow and red light. Loosely, the term crepuscular rays is sometimes extended to the general phenomenon of rays of sunlight that appear to converge at a point in the sky, irrespective of time of day. [3] [4]
Orange Skies Day was a climatological event that occurred in the San Francisco Bay Area on September 9, 2020.

Satellite flare, also known as satellite glint, is a satellite pass visible to the naked eye as a brief, bright "flare".It is caused by the reflection toward the Earth below of sunlight incident on satellite surfaces such as solar panels and antennas (e.g., synthetic aperture radar).
Residents in the provinces of the Eastern Cape, Western Cape and Free State reported seeing a bright blue-white and orange streak of light in the sky on Aug. 25, which was accompanied by an ...
The eerie scenes of orange skies have returned as Midwest cities like Chicago and Detroit, plus much of the Great Lakes region, found themselves shrouded in smoke from Canadian wildfires this week.
Sky brightness refers to the visual perception of the sky and how it scatters and diffuses light. The fact that the sky is not completely dark at night is easily visible. If light sources (e.g. the Moon and light pollution ) were removed from the night sky , only direct starlight would be visible.
