High-res photos of the Sun show what sunspots look like

The release noted that the “GREGOR telescope allows scientists to resolve details as small as 50 km on the Sun, which is a tiny fraction of the solar diameter of 1.4 million km. This is as if one saw a needle on a soccer field perfectly sharp from a distance of one kilometer.”

This was a very exciting, but also extremely challenging project. In only one year we completely redesigned the optics, mechanics, and electronics to achieve the best possible image quality,” said Dr Lucia Kleint, who led the project and the German solar telescopes on Tenerife.

Prof. Dr. Svetlana Berdyugina, professor at the Albert-Ludwig University of Freiburg and Director of the Leibniz Institute for Solar Physics (KIS) said that the “project was rather risky because such telescope upgrades usually take years, but the great team work and meticulous planning have led to this success. Now we have a powerful instrument to solve puzzles on the Sun.”

The new optics of the GREGOR telescope is said to allow scientists to study magnetic fields, convection, turbulence, solar eruptions, and sunspots in great detail. The images of the Sun reveal astonishing details of sunspot evolution and intricate structures in the solar plasma.
