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!
Genoa ( Genna ) is the capital of the Liguria region of Italy and the second most populous city after Milan. The city has a population of 219,599 (1 October 2014).
Genoa is located on the eastern coast of Italy, on the Gulf of Lion. The city stretches along the Gulf of Genoa and its southern tip forms the promontory of Liguria. Genoa borders the following Italian regions: Liguria, Piedmont, Lombardy, Emilia-Romagna and Tuscany. To the north, it is bordered by the Italian provinces of Vercelli, Biella, and Torino.
The city was an early Christian colony and has contributed significantly to Western art, literature and science. In the High Middle Ages, Genoa became one of the most prosperous centres of trade in Europe. It prospered in the Middle Ages as a commerce and shipping hub and its port played an important role in the maritime trade of Europe.
The citys historic centre, concentrated on the Naviglio Canal, is a UNESCO World Heritage Site. The city's new downtown area, the Business Square, was designed by the Swedish architectural firm MVRDV and was inaugurated in 2011.
Genoa is home to two of Europe's major football clubs, A.C. Milan and Juventus, and the local rugby union team, Zebre. The 1986 World Championship in Athletics was held in Genoa.
Tourist attractions in Genoa include the Palazzo Reale and the Castello Sforzesco, both UNESCO World Heritage Sites. Other attractions include the beaches of the Ligurian Coast, the Palace of Caserta and the Cathedral of Genoa.}
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.
