Diamond and Rubies - Many features of the Sun only become apparent during a total eclipse. This is a photograph taken at the moment when a tiny part of the Sun’s disc shines out between the mountains on the edge of the Moon, creating an effect known as the ‘diamond ring’. We see the Sun’s corona as a diffuse white haze, and closer in, the Sun’s chromosphere appears in the red light of hydrogen. Photo by by Tunç Tezel, Turkey.
Baily's beads during a total solar eclipse. The irregular landscape of the Moon means that its edge isn't perfectly smooth as it passes in front of the sun. It looks as if there are beads of bright sunlight coming through valleys and between mountains. They're named in honor of British astronomer Francis Baily who first explained them.
During a total lunar eclipse, the moon passes through the outer part of Earth's shadow, called the penumbra, and then into the dark umbra. When fully immersed in the umbra, the moon is in total eclipse or in totality. (Credit: Sagredo) Mona Evans, "Blood Moons and Lunar Tetrads" www.bellaonline.c...
