Researchers did not attribute the previously-seen description of the images to a major redesign of the telescope by scientists and engineers at the Leibniz Institute for Solar Physics (KIS). The new optics allow scientists to study magnetic fields, convection, turbulence, solar explosions and sunlight locations in greater detail than ever before.
Scientists said that, using GREGOR, they could study small details 30 miles up the surface of the sun – a tiny fraction of its 865,000-mile diameter. The researchers said, “It’s like someone saw a perfectly sharp needle from a distance of a kilometer on a football field.”
The sun extends from sunlight to solar storms and flares in many places – many of which are driven by its intense magnetic field. Not much has been understood about the magnetic field, so up-close images of the Sun’s surface are important to reveal its intricacies.
The researchers said the photos show “surprising” details of sunspot development and complex structures in solar plasma. Sunspots are temporarily darker regions due to the decrease in surface temperature due to magnetic field current.
“Was a very exciting, but also extremely challenging project. In just one year we completely redesigned optics, mechanics, and electronics, so that Dr. Lucia Clent, who led the project, said in a news. Skip
The team’s research was initially halted due to a coronovirus lockdown, but the researchers said they were eager to return to the lab when it reopened in Spain in July.
By knowing about the Sun’s magnetic activity, scientists will be able to better advise how to protect technology, such as satellites and our planet, from solar activity.
Director of KIS Drs. Svetlana Berdugina said, “This project was rather risky because such a telescope upgrade usually takes several years, but has been a success due to great team work and careful planning.” “Now we have a powerful tool to solve the puzzle on the Sun.”
