See the closest shots of the Sun’s surface

The GREGOR telescope, the largest in Europe, has made the most detailed images of the Sun’s surface and revealed the smallest features of the structure of its magnetic fields. They are published in the journal Astronomy & Astrophysics.

According to the researchers, the new optics of the GREGOR telescope will allow them to study in detail magnetic fields, convection, turbulence, solar flares, and spots.

It was a very exciting yet extremely challenging project. In just one year, we have completely redesigned the optics, mechanics, and electronics to achieve the best possible image quality.

The work was carried out to minimize the impact of extreme events on the Sun on humans, the operation of ground-based instruments and satellites in orbit, scientists must predict as accurately as possible the places of their appearance and power, and this requires a means of detailed observation of the Sun’s surface and its magnetic fields.

The new modernized telescope can distinguish features up to 50 kilometers across the Sun’s surface with a star diameter of 1.4 million kilometers. For comparison, it is like seeing the point of a needle on a football field from a distance of one kilometer.
