Solar Variability and Climate

In analyzing solar observations from the 19th century, scientists are turning to amateur researchers for help. The project will allow to better understand the history of our star. more

The longest-serving solar observatory in space has turned 25 and is still making significant contributions to solar research. Its old age has become an important merit. more

Dr. Yeo from the Max Planck Institute for Solar System Research investigates why and how much the Sun’s irradiance fluctuates.
