Need a little more Sun in your life?
German scientists have just upgraded a solar telescope called GREGOR at the Teide Observatory in the Canary Islands. The result is a spectacular new collection of images of our star.
“This was a very exciting, but also extremely challenging project,” said Lucia Kleint, scientist at the Leibniz Institute for Solar Physics in Freiburg and lead researcher on the project. said in a statement. “In just one year we completely redesigned the optics, mechanics and electronics in order to achieve the best possible image quality.”

GREGOR began its observations in 2012 as Europe’s largest Solar telescope The upgrade project began in 2018. The upgrades included working on the telescope’s optics and control systems, repainting the observatory to reflect less light and disrupting observations, and implementing new planning guidelines to improve the scientific results of observations.
Overall, scientists can now use the telescope to capture features on the sun that, according to statements, are only 50 kilometers in diameter. And since Solar activity is currently on the upswing When the minimum point of the current 11 year solar cycle ends, GREGOR will have a lot to study.
“The project was quite risky because telescope upgrades like this usually take years, but the great teamwork and careful planning have led to this success,” said Svetlana Berdyugina, astrophysicist at the Albert Ludwig University of Freiburg in Germany and director of the Leibniz Institute for Solar Physics said in the same statement. “Now we have a powerful tool for solving puzzles on the sun.”
The upgrades are described in a piece of paper published September 1 in the journal Astronomy & Astrophysics.
