What are the sunspots?
Sun spots are areas on the sun or surface that seem darker than the rest of the sun. Photosphere of the Sun or any gaseous celestial body is a layer of gases that form a visible surface. In the sun, the photosphere is extremely deep and stretches hundreds of kilometers. Under the photosphere lies the sun core, the powerhouse of the sun, which produces energy and heat. This is primarily the conversion of hydrogen into a helium in the form of a nuclear reaction. Sun spots excel in the bright surface of the sun and have been observed for thousands of years.
In the 16th century, the solar spots were more closely documented and generally accepted. Numerous writings and drawings from previous periods show that observers have seen obvious darkness on the surface of the sun. Sun spots look dark because they are cooler than the rest of the sun's surface, but they are actually very bright. They are irregularly shaped and tend to appear in clusters or in groups, always up to five to 35 degrees north and south of the sunshine.
causesThe sun spots are a magnetic storm. The stains serve as a visual indicator of increased magnetic activities in this area of the Sun and are commonly accompanied by ejects of coronal materials, better known as solar eruptions. Severe magnetic activity can affect life on Earth by disturbing communication and weather, and in the past it could lead to climatic anomalies.
The sun is not the only celestial body that has characteristic spots indicating magnetic activity. On other stars are dark brands known as "Starspots". In all cases, it seems to be running in cycles. The sun has an 11 -year sun cycle with a time of increased activity and at the end of the cycle. This cycle has been documented and studied since the 18th century, when astronomers began to explore multi -deck into a sunspots and solar system in general.
Sometimes the sun spots are so large that they can be seen with the naked eye even if it would causeDamage to the retina. However, the use of filters and a weak binoculars can detect sunspots during a period of high activity. The observatory of astronomy uses a heavy telescope and an equing cosmic vessel that helps them study solar spots. Published images of sunlight can be found, often with special filters applied to reveal sun flares and magnetic hot spots associated with sun spots.
