On Thursday, June 10, 2021, people across the northern hemisphere had the chance to experience an annular or partial eclipse of the Sun.
A solar eclipse happens when the Moon moves between the Sun and Earth, casting a shadow on Earth, fully or partially blocking the Sun’s light in some areas. During an annular eclipse, the Moon is far enough away from Earth that the Moon appears smaller than the Sun in the sky. Since the Moon does not block the entire view of the Sun, it will look like a dark disk on top of a larger, bright disk. This creates what looks like a ring of fire around the Moon.
In some places, viewers didn’t get to see this ring around the Moon. They instead experienced a partial solar eclipse. This happens when the Sun, Moon, and Earth are not exactly lined up. The Sun will appear to have a dark shadow on only part of its surface.
Roberto Frassi from Italy made use of this fact and layered the stacked results of 5 100-frame video’s to paint what resembles a tiara on the sun’s head.
