Europe’s largest solar telescope has captured new up-close images of the Sun, including magnetic storms on its surface.

Europe's largest solar telescope has captured new up-close images of the Sun, including magnetic storms on its surface.

The star can now be observed at a closer range following a redesign of the GREGOR telescope's optics.

"The GREGOR telescope allows scientists to resolve details as small as 50km on the Sun, which is a tiny fraction of the solar diameter of 1.4 million kilometres," the Germany-based Leibniz Institute for Solar Physics (KIS) said in a statement.

"This is as if one saw a needle on a soccer field perfectly sharp from a distance of one kilometre".

The telescope's new optics will allow scientists to study magnetic fields, convection, turbulence, solar eruptions, and sunspots in great detail.

The first light images obtained in July 2020 reveal astonishing details of sunspot evolution and intricate structures in solar plasma.

"This was a very exciting, but also extremely challenging project," team leader Dr Lucia Kleint said.

"In only one year we completely redesigned the optics, mechanics, and electronics to achieve the best possible image quality."

KIS director Professor Svetlana Berdyugina said the telescope had become a powerful new instrument to help solve "puzzles on the Sun".
