Foreign media disclosure: Some weird things are happening on the sun

According to the Australian scientific warning website recently reported, some weird things are happening on the sun. So far, almost every day in 2022, it is erupting in the form of spots and corona, some of which are the maximum intensity eruption that our stars can do.

As far as it is concerned, the eruption of the sun is not surprising. It will erupt regularly in the process of high activity and low activity in a period of about 11 years.

The current activity of the sun is significantly higher than the US National Aerospace Administration and the National Oceanic and Atmospheric Administration's official prediction of the current Sun cycle. Beginning from September 2020, the activeness of the sun has always exceeded the prediction level. However, a scientist who studies the sun will tell you that even this is not so strange.

Michael Whitland, a Sun celestial physicist at the University of Sydney, Australia, told the scientific warning website: "We cannot reliably predict the sun cycle."

Solar cycle

The solar cycle has a huge impact on the solar system, but is relatively unknown. Scientists have concluded that they seem to have inextricable connections with the solar magnetic field. The solar magnetic field covers the surface of the sun in the form of entanglement, vortex and ring -shaped.

About 11 years, the magnetic pole of the sun will flip, that is, the Arctic becomes Antarctic, and the Antarctic becomes the North Pole. This phenomenon of flipping is simultaneously occurred at the same time. The latter is characterized by the sunspots, the sun spots, and the daily coronal material throwing activity.

After this reversal occurs, the activeness of the sun weakens, and then it is strengthened to the peak period again. This is what we are currently in the current period of the current cycle. This is the 25th cycle of the Sun cycle.

Sun activity cycle is described and predicted based on one standard: the number of sun sunspots observed. The sun sunspots are some of the magnetic fields that are particularly strong, so that the spur and the daily coronal substances are thrown into temporary areas that are prone to eruption. They look like black spots, because the magnetic field suppresss the flow of hot ions, so these areas are lower than the area around them and they look dull.

According to Scott Mcingtos, a solar physicist at the National Atmospheric Research Center in the United States, predict that the solar cycle according to the number of sunspots in our statistics is problematic. He told the scientific early warning website: "The sun sunshine cycle is not a key issue. It is a secondary issue. The method of formulating the rules, the way of writing textbooks, and the way of presenting the sun activities are called the key. The key is the black cycle -22 years of magnetic cycle -is the key. And the sunspots are just one of the larger parts of this big picture. "

The Heir cycle was discovered by American astronomer George Elli Heier in the early 20th century. It includes two 11 -year sun sunspots cycles -that is, the two poles of the sun twice to return to the time required to return to their initial position.

In the case of the 11 -year Kuroko cycle, the Heier cycle can be observed through many phenomena. The polarity of Kuroko and Sun Magnets -and the intensity of cosmic rays to the Earth -are constantly changing.

The active of the sun makes it difficult for the universe rays to reach the earth, but the row and the raw ranking of the solar cycle have different cosmic radiation waveforms. This has always been attributed to the polarity of the solar magnetic field.

sunspot

What caused the sun sunspots? According to existing models, they are considered to be related to the rotation of the sun. The rotation speed of the solar equator is faster than the pole. If the straight magnetic field line walking along the vertical walking is to keep up with this rotation, then they will be stretched and eventually become entangled, which will produce a temporary and local strong magnetic field area, that is, the sun sunspot.

"About 60 years ago, in order to facilitate understanding, scientists had approximated these magnetic fields and believed that they were insignificant compared to the fluid on the sun. Therefore, when the sun circles Like the earth, the heating of the atmosphere will promote the circulation, and when this circulation continues, the magnetic field will be pulled and followed by the circulating. "

The animation that shows this effect is very good with the observation data of the sun sunspots -the initial magnetic field appears in areas with a latitude of about 30 degrees. However, according to Mcingtosh and his colleagues, this is because the purpose of the creation of this model is to explain this -and just this -phenomenon.

There is an interpretation of an alternative: the sun sunspots are the interference graphs generated by the overlapping Heier cycle. McKintesh and colleagues first noticed a obvious graphic in the Sun Kurosaki data in 2011, a overlap in the so -called butterfly map. The butterfly map is a black seed distribution map drawn with latitude as a vertical coordinate and time as a horizontal coordinate.

Magnetic field activity

Once these researchers see this phenomenon, they will find as much sunspots that they can get as much as possible and study. These data can be traced back to the 1860s.

They found that this overlapping continued. As the sunshine cycle is close to the end, as the sunspots look closer to the equator, they can observe the appearance of the sunspots belonging to the next cycle in the middle latitude region.

Researchers have found that these graphics represent the reverse polarized strip -like magnetic field activity that cross the sun in a cycle: they are the cause of the sunspot cycle of the sun, not affected by the cycle.In addition, these cycles can interact with: when the cycles with opposite polarity overlap, they will interfere with each other.The result of this interference is that their magnetic field systems inhibit the production of sunspots together, so they follow the period when the sun sunspots are the least activity.
