A black spot 800,000 km long on the Sun was discovered

According to CNN news agency, during a recent space trip astronauts from the US Space Agency (NASA) found a giant black spot on the Sun's surface. Black stain is a dark strip about 800,000 km long.

The most sophisticated helioseismology sensors that monitor the activity that takes place on the sun in the most specific way have captured the special image above. NASA experts are currently trying to understand the origin and analyze the nature of this unusual phenomenon.

According to the original hypothesis, the giant black spot can be traced to the accumulation of dense cold air, compressed on the celestial surface by magnetic fields, and the dark color of the crack may be due to temperature. It is much lower than the Sun's temperature.

And Rachel Howe and Frank Hill of the National Solar Observatory (NSO) in Tucson, Arizona, think the sun has produced narrow atmospheric currents near its poles over a 11-year cycle. These currents move slowly from 2 poles to the equator, and when a line reaches an important point on latitude 22, the sunspot of the new cycle begins to appear.

The two scientists also said that the solar-related flow recently moved abnormally slowly, taking up to 3 years to pass through 10 latitudes while in the previous cycle, this process is 2 years. .

In addition, atmospheric masses moving inside the sun also emit pressure waves and sounds as loud as a giant bell. By studying the vibrations of the solar surface, scientists will be able to detect the mechanism of action within it, providing precise diagrams of layers beneath the Sun.
