According to his report NASADark spots on the sun are the sun’s gases. They explain: “The sun’s gases are in constant motion tangle, stretch and distort magnetic fields. This motion creates a lot of activity on the surface of the sun called solar activity.” Despite the explanation, there was a lot of curiosity and concern about it. Learn more.
The dark spot on the sun is echoed online
Pictures of the sun with a giant dark spot have gone viral on the internet, after the images were posted by Girl In Space on Twitter.
The post’s caption read: “One of the largest sunspots in years, AR3190 (4 times wider than a land), crosses the solar disk and you can see it with the naked eye. Make sure to wear safety sunglasses to protect your eyes.
Girl In Space added: “The spot is about to explode. #AR3190 has an unstable ‘beta-gamma-delta’ magnetic field that harbors the energy for Class X solar flares. Any flares will be geo-influenced because the sunspot faces Earth almost directly. “
These sunspots are temporary, and they appear in the photosphere of the sun and their temperature ranges between 2000-4000 K, while the temperature of the material outside the sunspots is higher than 5000 K.
The decrease in temperature in these regions is caused by the presence of intense magnetic fields, which prevent the convection process of the solar photosphere, which reduces the flow of energy from the interior of the sun, and thus reduces the surface temperature of this region.
The spot is dark due to the fact that its surroundings are so bright that the local contrast causes us to perceive the spot as a black spot. Sunspots have lighter regions at the edges, which is due to a weaker magnetic field.
Do sun spots pose any danger?
This sunspot is not very dangerous, although it can explode at any moment. We are talking about a region of the sun with a large concentration of magnetic field. This matter is trapped in the form of plasma, which is a very hot and ionized gas.
These spots can cause a Category X explosion, which is an explosion that brings together very intense volcanic eruptions. Thus, radio waves, x-rays, and gamma rays can be released into space, possibly reaching Earth.
The consequences on the planet after being exposed to these rays are divided into two types: the formation of beautiful aurora borealis and the disruption of communication technologies, such as radios and satellites.
