The sun often produces hot plasma that rises from its surface, creating a massive ring-shaped "coronal ring." These rings are formed by electrons and protons moving in a spiral shape according to the sun's magnetic field and are primarily observed near the sun's surface. This photo was taken from Mantova, Italy, using hydrogen light to capture four coronal rings near the edge of the sun from last year to this year. These rings can vary in size from tens of thousands of kilometers to hundreds of thousands of kilometers, often larger than the size of Earth, and can last for several days. They frequently appear around sunspots and can sometimes burst, causing solar winds or solar storms that affect Earth.
