Hello fellow veterans, I believe many people do not know much about what sunspots are, so today I will share with you what sunspots are and what sunspots are about the sun. I hope this knowledge about what sunspots mean and what impact they have can help you solve some of your confusions. Let’s take a look below!

1. Characteristics of sunspots
Sunspots are not actually black, they are just cooler than their surroundings!
2. What do the sunspots in the sun mean
Sunspots that is! Sunspots are local areas on the sun\’s surface that appear \”dark\” due to relatively low temperatures. China is the first country in the world to discover sunspots. As early as ancient China, the Chinese at that time had discovered the existence of sunspots. Sunspots generally appear in groups on the surface of the sun, and astronomers call them \”spot groups.\” The formation cycle of sunspots is short. They will disappear within a few days to a few months after formation, and new sunspots will be produced again. Sunspots are an important symbol of solar activity, and their activities have obvious periodicity, with an average period of 11.1 years. Sunspot groups can cause interference to the Earth\’s magnetic field and ionosphere, and trigger auroras in the Earth\’s polar regions. Sunspots are composed of umbra and penumbra. The umbra is the particularly dark part. The penumbra is not too dark and is composed of many fibrous textures. When the number of large sunspot groups increases, it heralds drastic changes on the sun. Humans have discovered sunspot activity for thousands of years. The activity cycle of sunspots is 11.2 years. It will cause damage to the earth\’s magnetic field and various electronic products and appliances. In the first four years or so, sunspots continue to be produced, more and more, and the activity intensifies. The year when the number of sunspots reaches a maximum is called the peak solar activity year. Over the next seven years or so, sunspot activity gradually weakened, and sunspots became increasinglyThere are fewer and fewer sunspots, and the year when the number of sunspots is extremely small is called a solar activity trough year. Internationally, the sunspot cycle starting from 1755 is the first week, and then the sunspot cycle is arranged sequentially. 1999 begins in week 23.
3. Why do the sunspots of the sun look black
1. Sunspots are not really black, and the temperature is definitely not low. If you placed a sunspot in the night sky, it would glow a brighter crimson or orange color than the full moon!
2. The surface of the sun is about 5700°C. The sunspots are lower, between 3000 and 4500°C, so the sunspots are significantly dimmer than the surroundings, but only slightly lower. They contrast sharply with their surroundings, even to the human eye. Any sunspot appears dark relative to the rest of the Sun. Don\’t look directly at the sun with a telescope or anything else without a safe solar filter.
3. Astronomical images (like the awesome everyday images of the Sun) are often taken with filters that transmit specific wavelengths of light, which helps Plot the distribution of different elements. Some of these wavelengths may not even be visible light, so the only way to visualize them is to use false colors. Other scientific images are processed to enhance contrast or make subtle features more visible. Part of the role of science is to show us things we cannot see with our eyes alone. Scientists colored the image of the Sun orange because the Hubble Space Telescope cannot take color photos and uses filters at different wavelengths to take monochromatic images, which are more useful for research. But researchers also combine these filters to create beautiful photos that spark interest in the universe and perhaps attract funding for expensive telescopes.
4. Why is Heizi called Heizi
Heizi is Zhang Yonggang’s stage name , when he first debuted, he chose a stage name in order to impress everyone on him. He was not satisfied with many of the stage names at the beginning. Later, he thought of different stage names again and again, because he is from Liaoning and his skin is very dark and slow. Slowly, everyone was deeply impressed by him because of his appearance, and later called him the stage name Heizi. This stage name made him recognizable.
5. What does sunspot mean and what impact will it cause
On the photosphere of the sun, there are some vortex-shaped airflows, which look like a shallow disk with a concave middle.It\’s black, and these swirling airflows are sunspots. The sunspot itself is not black. The reason why it looks black is because its temperature is one to two thousand degrees lower than the light ball. Against the brighter light ball, it looks like there is no light. , dark sunspot. Sunspots are a type of solar activity that occurs on the photosphere of the sun. They are the most basic and obvious activity phenomenon in solar activity. It is generally believed that sunspots are actually huge vortices of hot gas on the surface of the sun, with a temperature of about 4,500 degrees Celsius. Because it is cooler than the surface of the sun\’s photosphere, it looks like dark spots. Sunspots rarely move alone. Often appear in groups. Sunspots are composed of the umbra and the penumbra. The umbra is the particularly dark part. The penumbra is not too dark. It is composed of many fibrous textures and has a swirl-like structure. When the large sunspot group has a vortex structure, it indicates that there will be drastic changes on the sun. Humans have discovered sunspot activity for thousands of years. The activity cycle of sunspots is 11.2 years. It will cause damage to the earth\’s magnetic field and various electronic products and appliances. In the first four years or so, sunspots continue to be produced, more and more, and the activity intensifies. The year when the number of sunspots reaches a maximum is called the peak solar activity year. In the next seven years or so, the sunspot activity gradually weakened and there were fewer and fewer sunspots. The year when the number of sunspots was extremely small was called a solar valley year. Internationally, the sunspot cycle starting from 1755 is the first week, and then the sunspot cycle is arranged sequentially. 1999 begins in week 23.
6. How many years do sunspots appear
Sunspots Although the activities are often unpredictable, in general, there is a certain regularity. The average lifespan of a sunspot is 11.1 years. In the first four years, sunspots continued to appear and their activity intensified. Over the next seven years, the activity of the Great Sunspot Group gradually weakened and disappeared.
The records of sunspots over the past 200 years since the invention of the telescope have confirmed that the sunspot activity cycle is 11.1 years, which is the 11-year sunspot cycle.
