According to the British newspaper “Daily Mail”, using the largest telescope in Europe, known as GREGOR, scientists have captured amazing details about the evolution of sunspots and the complex design of the solar plasma.
The largest telescope–
These are the highest resolution images observed by the European telescope, which the team attributes to new optics capable of examining the massive star’s magnetic fields, convection, solar flares and sunspots in great detail unlike ever before.
The images show solar magnetic fields captured at a wavelength of 516 nanometers and sunspots at 430 nanometers, which astronomers say is as if someone saw a needle on a soccer field from a distance of one kilometer.

The scientists added, “Our star is covered with many cell-like structures, each the size of the US state of Texas, and they are the product of violent convective movements that transfer heat from deep within the sun’s interior.”

In each of them the hot plasma rises in the bright center of the cell before it cools and descends again in the star to form dark corridors that GREGOR can see, and some have compared it to the appearance of popcorn.
“This was a very exciting project, but it was also very difficult,” said Dr. Lucia Clint, who led the project and the German solar telescopes in Tenerife.
“In just one year, we have completely redesigned optics, mechanics and electronics to achieve the best possible image quality,” Clint added.
