"Big rabbit, long time no see!"

Qiao Bao and Pink Moon greeted the big rabbit, and the big rabbit smiled softly at the two.

"Long time no see, Qiao Bao, congratulations on winning the first prize in the competition! Don't be proud, keep working hard, this is your little fan and sunglasses, take it! ”

"Thank you, Big Bunny!"

Qiao Bao and Fan Yue wore sunglasses and a small fan, and walked into the protective layer to observe the sun like a fireball from a distance.

"The Sun is a star located at the center of the solar system, and it is almost an ideal sphere intertwined with hot plasma and magnetic fields."

Qiao Bao and Pink Moon introduced the sun while looking at the situation on the surface of the sun displayed on the screen.

"The Sun is a huge, hot gas planet, but it is a very ordinary star in the universe.

Sunlight is the main source of energy for the Earth, and many natural synthetic processes can use solar energy, such as photosynthesis, which is the chemical extraction of energy from sunlight by plants.

Concentrated solar energy, such as energy stored in crude oil and other fossil fuels, is sometimes used, which comes from solar energy converted by photosynthesis in the distant past. ”

Fan Fanyue was still sweating with the fan, and turned his head to look at Qiao Bao, who was also hot and sweaty.

"You can only stay at the sun observation point for five minutes, otherwise it will really turn into a roasted sweet potato."

Pink Moon pulled Qiao Bao and hurriedly escaped, and rode around the spaceship into the introduction area, where there are many screens, respectively introducing sunspots, solar flares, light spots, rice grain tissue, solar wind, and coronal holes.

"Pink Month... What are these? ”

Qiao Bao looked at the screen curiously, although there were explanations from the big rabbit, but he just couldn't understand it.

"Solar flare is one of the most violent explosive phenomena that occurs in the local region of the sun's atmosphere, releasing a large amount of energy in a short period of time, causing instantaneous heating in the local area, emitting various electromagnetic radiation outward, and accompanied by a sudden increase in particle radiation."

Fan Fanyue patiently explained, although he just repeated the words of the big rabbit, but the speed of speech was a little slower, and Qiao Bao seemed to understand it.

"There are sometimes dark areas on the surface of the sun's photosphere, which is where the magnetic field gathers, and this is the sunspot. Sunspots are the most prominent phenomenon that can be seen on the surface of the sun.

Spot refers to the bright spot that appears on the edge of the sun's photosphere, where there are sunspots, but sometimes there are spots where there are no sunspots. ”

Qiao Bao nodded, suddenly pointed to the polygonal small particles that appeared on the screen, and said excitedly: "This is the rice grain tissue of the sun!" Take a good look! ”

"Yes, that's right."

Fan Fanyue nodded, "The rice grain tissue is a kind of solar structure on the sun's photosphere, and the temperature of the rice grain tissue is about 300 °C higher than the temperature of the inter-rice grain area.

Therefore, it is relatively bright and easy to see, although they are small particles, the actual diameter is 1000 km ~ 2000 km.

When the rice grain tissue rises to a certain height, it quickly cools and immediately descends along the gap between the updrafts, and its life span is very short.

The average lifespan is only a few minutes, and the ultra-rice grain tissue discovered in recent years has a scale of about 30,000 kilometers and a lifespan of about 20 hours. ”

"Qiao Bao is going to be dizzy, I don't understand very much."

Qiao Bao shook his head, this kind of knowledge is too difficult for himself!

"But I still want to hear it... Hey, hey, hey. ”
