The beautiful colors from a sunset are caused by the atmosphere. As the sun gets lower and lower in the sky, its light passes through more and more air layers—compared to noontime, when the sun is directly overhead. And those layers are filled with dust and water particles.
"At sunset the sky is full of pollutants and wind-borne particles," the authors write. On the other hand, more dust and smog (at sunset) can have the effect of scattering light across a greater region of the sky, creating a larger drape of colors, whereas sunrise colors tend to be more focused around the sun.
How to Predict Dramatic Sunsets
- Clouds and Cloud Cover. Clouds are a crucial factor to predicting dramatic sunsets, for without clouds there is not much to see.
- Clean Air. Clean air is very effective at scattering the blue light.
- Humidity. The amount of humidity in the air will also have an effect on the colors of your sunset.
- Wind.
When we see a red sky at night, this means that the setting sun is sending its light through a high concentration of dust particles. This usually indicates high pressure and stable air coming in from the west.
Keep Your Eyes Safe!
It is dangerous to stare directly at the Sun, even during sunrise or sunset. When using equipment that magnifies the sun, such as binoculars, a telescope, or even a telephoto lens, the time it takes to damage your eyes is much shorter.The blue color of the sky is due to Rayleigh scattering. As light from the sun shines down it scatters off of (mostly) nitrogen molecules in the atmosphere. Without this process, the sky would be dark during the day except for the bright sun, moon, and stars.
“Because the sun is low on the horizon, sunlight passes through more air at sunset and sunrise than during the day, when the sun is higher in the sky. More atmosphere means more molecules to scatter the violet and blue light away from your eyes. This is why sunsets are often yellow, orange, and red.”
Sonoran Desert skies are such a deep blue (to human eyes) because desert air is unusually pure, that is, compared to the air above many other places on the planet; it's relatively free of the tiny floating particles and droplets called aerosols.

Located over 200 miles north of the Arctic Circle, Tromsø, Norway, is home to extreme light variation between seasons. During the Polar Night, which lasts from November to January, the sun doesn't rise at all. Then the days get progressively longer until the Midnight Sun period, from May to July, when it never sets.
You can define twilight simply as the time of day between daylight and darkness, whether that's after sunset, or before sunrise. We have twilight because Earth has an atmosphere. Some light scatters through small particles in the atmosphere – so there's still some light in the sky even after the sun has gone down.
Why is it still "light" after sunset? As the sun goes further below the horizon, the scattering decreases (there's more earth in the way, so the light has to be scattered higher up in the atmosphere where the air is thinner) and it gets darker. The same thing happens in reverse before the sun rises.
Why Is It Still Light After Sunset? Even though the sun goes beneath the horizon, there is still light before it gets ideal for stargazing. And this is because of the spherical shape of the Earth and the Sun's distance of around 93 million miles away from the Earth.

In everyday language, the term dusk is commonly used as another word for evening twilight – the period from sunset until nighttime. Other colloquial synonyms include nightfall, sundown, and eventide. In some contexts, dusk is also used to denote the setting of the Sun.
Symbolism: A sunset represents ending, romance, twilight, beginning of darkness, change, transformation and nature. Calmly watching the sunset - Dreaming of watching the sunset means that you are stable in your life and you have left behind all the materialistic pleasures.

Answer: The Sun, the Moon, the planets, and the stars all rise in the east and set in the west. And that's because Earth spins -- toward the east.
The time of sunset is defined in astronomy as the moment when the upper limb of the Sun disappears below the horizon. Night occurs when the Sun reaches 18 degrees below the horizon and no longer illuminates the sky.
The sun rises first in japan and sets last in the tiny US territory of American Samoa, less than an hour away by plane to the south east, will take over as the last place on earth to see the sun set.
Roughly speaking, the golden hour is the first hour of light after sunrise and the last hour of light before sunset. So, there are actually two golden hours every day. However, this is just an approximation. Depending on the season and your location the golden hour might be a lot shorter or longer.
sunset is a noun: The time of day when the sun disappears below the western horizon.
See Sunset. The sunset is defined when the trailing edge of the sun disappears below the horizon, even though refraction means the sun actually went below the horizon some minutes before.
Once it has reached this lowest point, an interesting thing happens: the sun appears to stop moving south for three days. After this, the sun moves 1° north, announcing the coming of spring. It will continue to move northward until the summer solstice, when it reaches its highest point.
That's because of the variable rate of time it takes during the course of the year for Earth to turn all the way around to face the sun in the same place — say solar noon. Yet, because of the combination of the two effects, the time of sunset in Seattle holds steady between Dec. 5 and Dec.
The sun will never rise in the West. The sun will always rise from the same place as long as the earth turns in the same direction as it does today and the Earth will turn in the same direction as it does today at least until the sun explodes in about five billion years time.
Originally Answered: What would happen if the sun rose from the west? Reversing the rotation of the earth would have cataclysmic consequences. All tectonics would undergo severe strain resulting in massive volcanic activity. It would take millennia for things to settle down.
As the Earth moves around the Sun it rotates on its axis, so we have day and night. The side of the Earth facing the Sun is bathed in light and heat (daytime). The side of the Earth facing away from the Sun, out towards space, is darker and colder (nighttime).
Also, latitude comes into it as the earth's axis is tilted at 23.4° so in summer in the northern hemisphere, places further to the north will experience sunrise earlier and sunset later than somewhere further south. In winter, this is the opposite, places further south see sunrise earlier and sunset later.
Just like at the North Pole, it's a constant sunset. The only difference is that the Sun is in the Northern sky, not the South. At the winter solstice (which is June 21st in the Southern hemisphere), the Sun still goes from east to west.
