Recently, scientists have revealed the incredible complexity of the sun’s surface, including high-resolution images of sunspots, through some groundbreaking close-up images of the sun. In July 2020, the European Gregor solar telescope team at the Ted Observatory in Spain aimed its latest high-precision instrument at the sun and made an unprecedented observation on it. < / P > < p > although it may be the nearest star to the earth, the observation of the sun is still a challenge. On the one hand, there are ongoing projects to send the probes to the star, despite the considerable challenge of successfully making a journey of about 93 million miles. On the other hand, there are high-power telescopes, but they also encounter their own obstacles. At such distances, even the smallest optical problems can lead to blurring or focusing problems. In fact, it was at the same time that the Gregor team made a new imaging breakthrough. < / P > < p > “in just one year, we have completely redesigned optics, mechanics and electronics to achieve the best image quality.” The project leader, Dr Lucia kleint, explained. The breakthrough is a combination of hardware and software, using optical models to create complex off-axis parabolic mirrors, which will help to give Gregor incredible magnification. In the process, these need to be polished to an accuracy of 6 nanometers, or about 1 / 10000 of the diameter of a human hair. < / P > < p > the reconstruction work will be completed in March 2020, but the bad weather means that the observation results will not be recorded until July. However, the results are worth waiting for. Gregor is able to parse details as small as 31 miles on the sun, which is 865370 miles in diameter. < / P > < p > “the telescope’s new optical technology will enable scientists to study magnetic fields, convection, turbulence, solar eruptions and sunspots in great detail,” the team said. “The first optical image obtained in July 2020 reveals amazing details of sunspot evolution and complex structures in solar plasma.” Global Tech
