Recently, scientists have revealed the sun’s incredibly complex surface with some ground-breaking close-up images of the sun, including high-resolution images of sunseeds,media reported. The Team of the European GREGOR Solar Telescope at the Ted Observatory in Spain made an unprecedented observation of its latest high-precision instrument at the sun in July 2020.
Although it may be the closest star to Earth, sun observation remains a challenge. On the one hand, there are ongoing projects to send probes to the star, although they face the challenge of successfully carrying out a journey of about 93 million miles. On the other hand, there are high-powered telescopes, but they also encounter their own obstacles. At such distances, even the tiniest 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.
“In just one year, we have completely redesigned optics, mechanics and electronics to achieve the best image quality.” Project leader Dr. Lucia Kleint explained. This breakthrough is a combination of hardware and software that uses optical models to create complex off-axis parabolic mirrors that will help give GREGOR incredible magnification. In this process, these need to be polished to an accuracy of 6 nanometers, or about 1/10000 of the diameter of a human hair.
Reconstruction will be completed by March 2020, but bad weather means that observations will not be actually recorded until July. However, the results are worth waiting for. GREGOR is able to parse details as small as 31 miles on the sun, and its diameter is 865,370 miles.
“The telescope’s new optical technology will allow scientists to study magnetic fields, 2x, turbulence, solar eruptions and sunseeds in very detail,” the team said. “The first light image obtained in July 2020 reveals amazing details about the evolution of sunsurgers and the complex structure of the sun’s plasma.”
