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!
Boston, MA, nicknamed the “City of Presidents,” was founded in 1630 and served as the capital of the United States from 1785-1790. Boston is the largest city in New England, located on the Atlantic coast west of the dogleg bend in the Charles River, north of downtown Boston and south of Worcester. The city has an estimated population of 658,701 as of 2016.
Boston is located on the northeastern slopes of the Blue Hills, approximately 40 miles west of Providence, RI and 125 miles south of Montreal, Quebec. It has a temperate climate with strong seasonal variations, with hot, humid summers and cold, damp winters.
Notable attractions in Boston include the Freedom Trail, Fenway Park, the USS Constitution Museum, the Boston Tea Party Museum, the John F. Kennedy Presidential Library and Museum, and the Torontonometro Exhibition Center. The city's skyline is dominated by the dramatic presence of the Paul Revere Memorial Tower and the inspiring sight of the John F. Kennedy Presidential Library and Museum.
There are several colleges and universities in Boston, including Boston University, Northeastern University, Emerson College, and MIT. Several Fortune 500 companies are also headquartered in the city, including Microsoft, Google, and HP. Boston is served by both Amtrak and the MBTA commuter rail system.
}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.
