At dusk and dawn the colors of the sky change and the first portion of the visible spectrum is what appears to the viewer. During these times of the day the sun is positioned at a different angle to the earth than during the normal daytime. Because of this angle, the longer wavelengths are the ones that reach the eye. The blue and other shorter wavelengths are scattered millions of times and do not reach the viewer. When the sun does not shine directly on a certain portion of the earth there are more gas molecules between the viewer and the sun. Therefore, the normal blue color of he sky is no longer visible because the short wavelengths of blue and green are scattered millions of times and do not reach the viewer

∙ 15y agoThe sky is blue because of a phenomena called rayleigh scattering. Basically sunlight is composed of shortwave blue light and longwave red light. The atmosphere permits all the light to pass through but the shorter wavelengths are also scattered "painting" the sky blue.
During sunset and sunrise the light travels through a longer path to reach our eyes, so the longer wavelengths also scatter - creating red skys.
The sky is black at night because there is no light to pass through it and scatter.

∙ 14y agoWhen the sun as at a low angle in the sky, the light travels through more of the atmosphere, causing more coloring of light. The sunlight that does not travel directly to the observer is scattered by particles in the atmosphere, causing diffused light in the whole area of the sky.

∙ 14y agoWe know that, the Earth travlls through space by rotating on its axis, and revolving around the Sun on its orbit. We can hardly feel the planet moving, lly observe the but can percieve it by observing the celestial bodies in the sky. We notice the Sun changes its position in the sky throughout the day. It is due to the motion of Earth that the Sun appears to be moving, As Earth moves inits orbit, its position with the Sun, other Planets, and stars keeps changing, and that is why we notice a change in the topography in the sky throughout the year. There are two kind of changes that we see in the sky-daily changes, and yearly changes. If we carefully observe the sky at different times over the year, we would notice different stars and constellations. While trevelling in its orbit.Earth faces comets, planets, stars and other celestial bodies in various parts of the universe, and thus, the sky changes as the planets moves on its yearly path.
