Darkness
Most people know that sunset is the time when the sun goes down. But did you know that the sun doesn't actually set? Instead, Earth rotates into darkness, giving us the illusion that the sun is setting. So what causes sunset?
Well, it's a combination of things. The Earth's atmosphere scatters sunlight in every direction, but blue and violet light are scattered more than other colors. This is why the sky is usually blue during the daytime. As the sun gets lower in the sky, the atmosphere becomes thicker and more dense.
This scattering of sunlight happens to a greater extent, and we see red and orange light more than blue and violet light. That's why sunset is usually a beautiful red or orange color. So next time you see sunset, remember that you're actually seeing Earth rotate into darkness!
Palermo is a Mediterranean city located on the south coast of Sicily, Italy. Geographically located in the upper part of the Sicilian Mediterranea, Palermo is bordered by the Tyrrhenian Sea to the west and the Ionian Sea to the south. The city has a population of about 1,315,000 people. Palermo is the capital of both the autonomous region of Sicily and the Metropolitan City of Palermo, which has a population of over 3.2 million. The city is known for its art, history, fashion, and food.
The area of what is now Palermo has been settled for over 8,000 years. The Palermitans, a Phoenician people, first established a small port on the coast in the 8th century BCE. The city grew rapidly, and by 600 BCE, it had become an important center of trade in the Mediterranean. In 418 BCE, the city was sacked by the Carthaginians, who ruled the island until the Second Punic War in 149 BCE. The city rebelled against the Roman Republic, and in the 5th century, it was sacked by the Goths. In 730, it was conquered by the Arabs, and in 965, it was ruled by the Emirate of Sicily.
Palermo became an autonomous municipality in the mid-15th century. It passed to the Crown of Aragon in the 15th century, and then to the Republic of Genoa in the 16th century. In 1860, Palermo was invaded by the Kingdom of Italy. In 1946, it became an autonomous region, and in 1963, it became a Metropolitan City. Palermo is noted for its art, history, fashion, and food. The city is home to several cultural institutions, including the national art museum, the national opera house, and the national library.
}As the sun sets, the sky slowly grows dark. For many people, this is a time to relax and wind down for the day. But have you ever wondered exactly when it gets dark? The answer may surprise you.
Did you know that darkness actually begins long before the sun sets? As the sun gets lower in the sky, its light has to travel through more atmosphere. This filters out some of the blue light, making the sun look redder. At the same time, shadows get longer and darker. So by the time the sun finally dips below the horizon, darkness has already begun to fall.
Of course, not all places on Earth experience darkness at the same time. Near the equator, the sun sets and rises almost directly overhead. This means that there is less of a difference between daytime and nighttime. Closer to the poles, however, the sun stays low in the sky for much of the year. This leads to longer periods of darkness during wintertime.
