Sunspot imaged by the GREGOR telescope
Sunspot imaged by the GREGOR telescope A sunspot observed in high resolution by the GREGOR telescope at the wavelength 430 nm. The GREGOR telescope is the largest solar telescope in Europe, and is operated by a German consortium and located on Teide Observatory, Spain. It 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. Leibniz Institute for Solar Physics
